Let me create a beautiful SVG illustration.

Key requirements:
- viewBox 0 0 800 600
- Hand-written shapes only
- Fox: pointy ears, snout, bushy tail with white tip
- Moon with soft glow, many stars, hill, background elements (trees, distant hills)
- Coherent palette, at least one gradient
- Animations: stars twinkling, tail swaying, shooting star every 4s with first within 2s

Let me design.

Palette: night sky deep indigo → violet gradient. Moon pale cream/soft yellow with glow. Hills in dark teal/indigo. Fox in warm orange (#E8843C / #F2A05A) with cream belly and white tail tip. Stars in pale gold/white.

Composition:
- Sky: rect 0 0 800 600 with gradient from #0B1033 top to #2A1B4A / #3D2A5C near horizon.
- Stars: many circles with twinkle animation (CSS @keyframes with opacity), randomized delays.
- Moon: at (620, 140) radius ~48, with radial gradient glow circle, crater details subtle.
- Distant hills: path shapes around y=380-430, muted purple.
- Mid hills / tree line silhouette.
- Foreground hill: large curve from bottom, dark green-ish/navy, where fox sits.
- Fox: sitting on hill, facing right looking at moon (moon at upper right). Fox at around x=280, y=430.

Fox construction (facing right):
- Body: sitting posture. Tail curls around front/left.
- Head: circle-ish with pointed snout going right.
- Ears: two triangles with inner pink.
- Eye: small dark almond, white glint.
- Nose: small dark circle at snout tip.
- Chest/belly cream.
- Front legs: two vertical cream/dark shapes.
- Tail: big bushy shape sweeping from rear (left) up and around, white tip.

Tail sway animation: rotate around base point using CSS transform with transform-origin. Use `transform-box: fill-box`? Better use transform-origin in user units: `transform-origin: 250px 470px;` with CSS in SVG works in Chrome. Actually CSS transform-origin with px units refers to the SVG user coordinate system relative to the element's reference box (default view-box for SVG elements in Chrome? The default transform-box is view-box for SVG elements per spec: `transform-box: view-box` is the initial value). So transform-origin: 250px 470px would be in the viewBox coordinate space. Yes, initial transform-box is view-box. Good.

But careful: the tail needs to sway gently. Let's build the tail as a group with the base at the fox's rear, around (250, 465). Rotate ±4 degrees.

Also perhaps animate the fox's ear slightly, or blink the eye.

Shooting star: an element (line with glow) that translates across sky every 4 seconds. Use CSS animation with keyframes: 0% opacity 0 translate at start position; 5% opacity 1; 60% opacity 0 and translated far; then stays invisible until next cycle at 100%. Duration 4s, first shot must appear within 2 seconds — so animation should start near beginning: e.g., 0% invisible at position A (off-screen left up), 8% visible, 40% faded far away, then hidden till 100% where it resets to A. That gives first shooting star crossing starting ~0.3s. Good, and loop period 4s.

Let's make the shooting star travel from top-left area toward lower-right? Typically from upper-left to lower-right diagonally. Let's start at (-60, 80) and go to (700, 300)? That crosses sky. Hmm, but moon is at top-right. Let's make it travel from (-40, 60) to (600, 260) with fade. Use two: a bright head and a tapering tail (use a path with gradient or a polygon).

Implementation: group with transform translate. Draw a path: from head at (0,0) trailing back to (-70, 30) with a tapered shape. Use path "M0,0 L-80,34 L-78,20 Z" hmm. Better: draw a line from (0,0) to (-85,32) with stroke gradient and stroke-linecap round, plus a small bright circle head.

Alternatively use a polygon: M 0 0 L -12 -3 L -90 -38 L -78 -25 ... Let's just do: head circle r=3 fill #fff, tail: path d="M-2,-2 L-95,-40" stroke url(#shootGrad) stroke-width 2.5 linecap round, plus a softer wider stroke underneath.

Actually simpler: polygon taper: points (0,0), (-8,-4), (-100,-42), (-92,-36), (-4,4). Let's do path "M0,0 L-96,-40 L-84,-36 L-6,3 Z" roughly a tapered sliver. I'll do: d="M0,0 L-100,-42 L-88,-33 L-8,4 Z" fill gradient white→transparent. Fine.

Also add a subtle "sparkle" burst where it starts maybe.

Stars: generate many with varied size and animation delays. Twinkle: opacity 0.25→1 and scale? Use animation on opacity only plus slight. To avoid many CSS classes, define one keyframe "twinkle" and apply with inline style animation-delay and animation-duration variations via classes .t1 .t2 .t3.

I'll write ~70 stars manually — that's a lot of typing but fine. Let me place them pseudo-randomly but avoid moon area and lower region.

Let me also add a few "sparkle" 4-point stars (path cross shape) that pulse.

Distant hills: 
- Far hills: path across at y ~ 400, fill #241B47 / gradient.
- Tree line silhouettes on distant hill: simple triangular pines.
- Background trees on foreground hill: a couple of pines at right and left.

Foreground hill: big curve from (0,600) up. Fox sits on crest at around x=300, y=470.

Let me set foreground hill crest: path M -20 600 C 120 520, 200 470, 330 452 C 460 436, 620 470, 820 430 L 820 620 L -20 620 Z. Hmm need fox to sit on crest. Let's simplify: foreground hill path M0,600 L0,520 C120,480 220,455 320,452 C470,448 640,480 800,455 L800,600 Z. Fox at x≈300, baseline y≈452.

Fox sitting: Let's define coordinates. Ground contact y = 452. Fox sits upright, facing right.

Fox body (sitting, side-ish view facing right):
- Rear/haunch: big rounded shape at left: circle-ish around (285, 405) radius ~45.
- Body shape overall: from haunch rising to chest at (340, 370).
- Head: center around (360, 330), radius ~30; snout extends right to (400, 342).
- Ears: triangles above head.

Let me draw with paths.

Sitting fox silhouette (facing right), overall:
- Haunch (rear leg) circle center (287, 412) r=42.
- Body/chest: path from rear up to shoulders and down to front legs.

Simpler approach: build the fox as one main body path, then add details.

Body path:
```
M 300 452
C 296 430, 292 405, 300 385
C 306 366, 320 352, 338 350
C 360 348, 372 366, 372 390
C 372 412, 368 432, 364 452
Z
```
That's a torso from ground up to shoulders at y=350.

Haunch: ellipse cx=300 cy=408 rx=38 ry=44 — overlapping merges look okay if same fill. Use a path instead to keep clean edges; overlapping ellipses with same fill create visible seam only if stroke. Without stroke it's fine visually (same color). I'll avoid strokes mostly.

Chest/cream bib: path from neck down front: 
```
M 352 352 C 368 356, 374 380, 370 400 C 366 418, 358 434, 352 452 L 332 452 C 342 424, 346 400, 344 378 C 343 364, 346 355, 352 352 Z
```
Hmm, better: cream chest shape following front of torso.

Front legs: two narrow shapes from chest down to ground:
path M 346 400 L 362 400 L 366 452 L 348 452 Z (front leg) — with paw.
Second front leg slightly behind: M 336 402 L 350 402 L 352 452 L 338 452.

Hind foot at bottom: ellipse at (300,448) rx 22 ry 9.

Head: 
- Head shape: rounded with snout. Path:
```
M 330 336 C 326 316, 340 300, 360 300 C 378 300, 390 312, 392 326 C 404 328, 414 332, 418 340 C 420 346, 416 352, 408 352 C 396 352, 388 350, 382 348 C 378 356, 368 360, 358 358 C 344 355, 333 348, 330 336 Z
```
Hmm, let's think: head centered (360, 325), snout pointing right ending at (425, 340). Ears at top around x 345 and 375.

Head path attempt:
```
M 332 330
C 330 310, 344 296, 362 296
C 380 296, 392 308, 394 322
C 412 326, 428 334, 434 342
C 437 347, 433 354, 425 354
C 414 354, 404 351, 396 348
C 392 358, 380 364, 366 362
C 348 360, 334 348, 332 330
Z
```
Ears: left ear (far, behind) triangle: M 340 302 L 336 268 L 362 292 Z (pointing up-left). Right ear (near): M 372 296 L 382 262 L 396 296 Z? Ears should be prominent triangles with pink inner.

Let's define near ear: base points (356, 300) to (388, 296), apex (378, 258). Path M356,300 L378,258 L390,300 Z — hmm need it attached to head. Use: M 352 302 L 374 256 L 392 300 Z.
Inner ear: M 360 298 L 374 264 L 384 298 Z fill #6B3546 (dark rose) or pinkish #C97B78.

Far ear slightly smaller and darker: M 334 302 L 348 262 L 364 300 Z fill darker orange (#C9702F).

Eye: near eye at (376, 322) — almond: ellipse rx 5 ry 6 fill #2A1A2E, plus white glint circle r 1.6 at (378, 320). Far eye maybe not visible in side profile; optional small dark dot at (352,320)? For a 3/4 view, one eye visible is fine. Let's do profile with one eye visible.

Actually a nicer look: fox in profile facing right, one eye. Good.

Nose: small rounded triangle at snout tip (432, 344): path M 426 338 L 438 344 L 426 350 Z fill #2A1A2E. Place at end of muzzle ~ (433,343).

Cheek/ruff cream: cream fur around cheek and jaw: path under head:
```
M 348 348 C 356 358, 372 362, 384 356 C 378 364, 362 366, 352 358 Z
```
Maybe simpler: cream muzzle patch from eye down to chin and back along jaw.

Muzzle cream: path M 396 330 C 410 330, 428 336, 434 342 C 437 347, 433 354, 425 354 C 414 354, 404 351, 396 348 C 392 342, 392 334, 396 330 Z — cream #F6EBD8 covering lower muzzle. Hmm careful with nose on top.

Jaw/cheek cream lower part of head: M 344 344 C 350 356, 366 364, 382 360 ... Let's include a cream cheek sweep: from under eye area down to chin:
```
M 352 336 C 352 350, 362 362, 378 362 C 392 362, 404 356, 410 350 C 404 360, 390 368, 374 368 C 358 368, 348 354, 352 336 Z
```
That might be too fiddly. Alternative: draw cream shape under head using a simple rounded blob that reads as cheek ruff.

I'll craft: cream ruff path:
```
M 344 334
C 342 350, 348 364, 362 370
C 378 376, 396 370, 404 358
C 398 372, 386 380, 368 380
C 350 380, 338 366, 338 344
Z
```
This gives a crescent along the lower-left of head. Good.

Tail: bushy, from rear of body sweeping left and up, curling. Base at around (275, 430) near haunch. Tail path going left and curving up to tip at (185, 370) with white tip.

Tail shape: 
```
M 272 440
C 236 442, 196 428, 176 402
C 158 378, 162 348, 182 338
C 196 331, 210 338, 208 350
C 206 362, 196 368, 190 378
C 204 396, 232 408, 268 414
Z
```
Hmm, that's a loop. Let me instead make a classic bushy tail: big teardrop from hip going left, curving upward with tip pointing up-right near the back.

Simpler: tail as a thick curved shape:
```
M 282 448
C 240 450, 200 436, 180 410
C 162 386, 166 356, 188 346
C 200 341, 210 348, 208 360
C 207 370, 200 376, 196 384
C 206 402, 234 416, 278 420
Z
```
This creates a crescent sweeping left then tip curling up at (208,360). White tip: a smaller shape at the end: 
```
M 208 360 C 207 370, 200 376, 196 384 ... 
```
White tip portion: path covering region around (188,346)-(208,360)-(196,384):
```
M 208 360 C 207 371, 199 378, 194 386 C 202 392, 212 390, 216 380 C 222 366, 216 348, 200 344 C 190 341, 180 346, 178 356 C 186 346, 200 348, 208 360 Z
```
Getting complicated. Let's design tail as a stroke-based shape? Alternative: use a filled path for whole tail in orange, then overlay a white tip path that shares the tip boundary.

Cleaner approach: define the tail as a closed path going: start at base bottom (280, 446) → outer edge leftwards and up to tip (200, 330) → inner edge back down to base (272, 418). Then white tip = the region of that path near the tip, defined by a separate closed path that matches the outer/inner edges near the tip.

Let me define outer edge: from (280,446) curve to (185,405) to (172,362) to tip top (196,328). Inner edge from tip (196,328) curve back: (176,352) (190,378) (215,392) (250,400) (274,414) close.

Full tail path:
```
M 280 446
C 240 448, 200 434, 180 410
C 162 388, 160 352, 196 328
C 186 344, 186 366, 198 380
C 212 396, 240 404, 272 414
Z
```
Wait the inner edge should be inside the tail shape (tail thickness). The outer edge goes from base leftward-up to tip at (196,328); inner edge returns from tip down to base at (272,414). Using control points: C 186 344, 186 366, 198 380 then C 212 396, 240 404, 272 414. That yields a crescent. The tail will be a crescent moon shape sweeping left and up. Tip at (196,328) pointing up. Good — but the tip should be the pointy end. At (196,328), outer edge arrives from (180,410) direction and inner leaves toward (186,344): fine.

White tip: region between the tip and a cut line. Take the same curve and a cut across: 
```
M 196 328
C 186 344, 186 366, 198 380
C 188 378, 178 362, 176 346
C 176 336, 184 330, 196 328
Z
```
Hmm, this white tip shape: the tip region of the crescent between outer edge (left/bottom) and inner edge. The cut line goes from around (176,346) to (198,380). So white tip = path from tip (196,328) along inner edge down to (198,380), then across cut line to (176,346), then along outer edge back up to tip. Outer edge between (180,410) and tip passes near (176,346)? Outer edge: C 162 388, 160 352, 196 328 — points around x≈166-180 at y 352-380. So the outer edge near y=346 is around x=170. Hmm, my cut point (176,346) approximately on the outer edge. Good enough, small discrepancy won't be noticeable since white shape overlays orange.

Let me just draw white tip as:
```
M 196 326 C 184 330, 172 340, 170 354 C 169 366, 176 378, 188 384 C 184 372, 184 356, 190 344 C 193 336, 195 330, 196 326 Z
```
Eh. I'll take a simpler approach: draw white tip as a separate shape shaped like a teardrop that overlaps the tail tip, extending slightly beyond so it forms the point:

White tip path:
```
M 198 320
C 210 324, 214 340, 210 352
C 206 366, 196 376, 184 380
C 176 368, 176 350, 184 338
C 189 330, 193 323, 198 320
Z
```
That is a blob around (196,348) — it would cover the tip region of the orange crescent. The orange crescent tip at (196,328) would be inside white blob? The blob spans y 320-380, x 176-214. The crescent at that region: outer edge x≈166-186, inner edge... The blob might cover the tip and a bit beyond, making a nice white tuft. I think that works visually: a white bushy tip.

But careful: the white blob may extend left of the orange crescent's outer edge (x 176 vs outer edge ~168 at y=350) — slight overflow is okay-ish but might look like a separate blob. I'll tune: keep blob x from 172 to 208.

I'll go with:
white tip: M 197 318 C 209 322, 213 338, 209 351 C 204 366, 193 377, 181 381 C 174 369, 173 352, 180 339 C 185 329, 191 322, 197 318 Z

And the orange tail crescent:
M 280 446 C 240 448, 200 434, 180 410 C 162 388, 160 352, 196 328 C 186 344, 186 366, 198 380 C 212 396, 240 404, 272 414 Z

White tip covers around (180-209, 318-381) which covers the crescent's tip region (tip at 196,328) and inner-edge start. Slight mismatch: inner edge from tip goes down-right to (198,380) which is inside the white blob region? Blob's right boundary at y=380 is x≈181... Hmm, so orange inner edge visible between white and orange? The white blob spans x 173-213 at y 340-360. The crescent inner edge from (196,328) toward (198,380) — at y=350, inner edge x ≈ 189 (roughly), which is inside blob (blob at y=350 spans 174-209). Good. So white covers the inner edge region. Fine.

Honestly, fine-tuning without rendering is risky but the overall silhouette matters most.

Tail sway: wrap the tail group with animation rotating about base (272, 440) by -3 to +3 deg. But rotation in CSS transform with transform-origin at (272,440) using user units and transform-box: view-box. Let's set on group: style="transform-origin: 272px 440px; animation: tailSway 5s ease-in-out infinite;" keyframes rotate(-3deg) → rotate(3deg).

Careful: CSS transform on SVG elements in Chrome works. transform-box initial value is view-box per CSS Transforms Level 2? Actually the initial value of transform-box is `view-box` per spec (changed from border-box). Chrome implements `view-box` as initial? Let me recall: Chrome's initial value for transform-box is `view-box` since Chrome 118-ish? Older Chrome used `border-box`. Hmm. To be safe, explicitly set `transform-box: view-box;` on the animated group. That works in Chrome.

Alternatively use SMIL <animateTransform type="rotate" values="-3 272 440; 3 272 440; -3 272 440"> — that's explicitly in user space, guaranteed. SMIL rotate with center given works. Safer! Use SMIL for the tail.

But CSS animations for star twinkle are fine (opacity only). Shooting star: use CSS transform translate with transform-box view-box, or SMIL animateTransform translate with values and keyTimes, plus opacity animation. SMIL is robust: I can do:

<g opacity="0">
 <animate attributeName="opacity" values="0;1;1;0;0" keyTimes="0;0.03;0.12;0.35;1" dur="4s" repeatCount="indefinite"/>
 <animateTransform attributeName="transform" type="translate" values="-40,60; 0,0; 120,40; 420,150; 520,180" keyTimes="0;0.03;0.12;0.35;1" dur="4s" repeatCount="indefinite"/>
 ...
</g>

Wait, values with 5 keyTimes need matching count. Let's use values="0,0; 40,20; 420,150; 520,185" keyTimes="0;0.06;0.32;1" and opacity values="0;1;1;0;0" keyTimes="0;0.04;0.1;0.3;1". The translate should span from start position (group drawn at origin, say at (0,0) with the streak going up-left) — I'll position the streak shape at coordinates relative: head at (0,0), trail to (-90,-38). Then translate from (-60, 90) to (620, 250) over the cycle.

Timing: first shot within 2 seconds: with keyTimes opacity 1 at 4% of 4s = 0.16s. Good, shot starts almost immediately and travels until 0.3*4=1.2s then invisible until next cycle at 4s. Every 4 seconds. 

Add also a second faint shooting star offset? Requirement says a shooting star every 4 seconds; one is enough but two staggered would look nice — but "every 4 seconds" spec. I'll do one main shooting star plus maybe a tiny sparkle burst. Keep one, plus maybe a second dimmer one at +2s offset for richness? That could violate "every 4 seconds"? It'd still be every 4s for each. I'll add one primary at 4s and one secondary with begin="2s" also dur 4s so they alternate every 2s. Hmm, that means a shooting star appears every 2 seconds. The requirement is a shooting star crossing every 4 seconds with first within 2 seconds. Adding a second might be seen as extra. I'll keep just one to be safe, maybe with a small sparkle burst at its start.

Also animate: moon glow pulse (very subtle), and fox ear twitch maybe. Fox blink: eye scale/opacity — do a CSS animation on eye group with scaleY? Use SMIL on ellipse ry: values="6;6;0.6;6;6" keyTimes="0;0.9;0.94;0.98;1" dur="6s". Simple.

Stars twinkle: CSS @keyframes twinkle {0%,100%{opacity:.35} 50%{opacity:1}} applied to circles with varying duration/delays. But I want random-ish; I'll use three classes with durations 2.5s/3.7s/4.6s and delays.

Star field: I'll write ~60 small circles. Let me generate positions manually in a grid-ish random pattern.

Also 5-point "sparkle" stars (4-point crosses) larger with pulse animation.

Background elements: 
- Far mountain range (two layers) in dark purple silhouettes with a slight gradient.
- Tree line: small pines on far hill.
- A few larger pine trees on foreground hill left and right edges, dark silhouettes.

Foreground hill: gradient from #1B2B3A? Palette coherence: sky deep indigo #0E1230 → #2B1E4E → horizon #4A2B57? Hills: far #3A2A5C, mid #2A2149, near #18203C / #101A2E. Trees #0E1526. Fox orange #E07A3C with lighter #F0995A highlights, cream #F7E7CE, dark #241A2E for nose/eye.

Grass tufts on foreground hill in a slightly lighter tone, plus small flowers maybe with subtle sway animation.

Also light: moonlight rim on fox? Could add a soft lighter edge on fox's back/head facing the moon (moon is up-right). Add a highlight shape: a light stroke along the back and head top with fill #FFD9A0 at low opacity. Nice touch.

Let me write the SVG.

Structure:

```

Moon: position (620,140), r=46. Glow circle r=150 with radialGradient.

Craters: subtle circles fill #E8D9B4 opacity .5 at moon surface.

Fox highlight rim: path along head top and back, stroke #FFD9A0 opacity .55 width 3, linecap round — moon at upper right so light from upper-right. Fox facing right, head upper-right. So rim on head top-right and back-right, tail top-right.

Let's write it.

Stars list — I'll produce coordinates. Avoid the region around moon (radius 150 around (620,140)) i.e. x 470-770, y -10..290 partly. And avoid the shooting star path maybe not needed.

Let me create star positions (x,y,r):
Row y ~ 20-40: (40,32,1.6)(95,18,1.1)(150,44,1.3)(210,26,1.0)(265,52,1.5)(320,30,1.2)(380,48,1.4)(440,20,1.1)(500,36,1.3)(740,22,1.5)(780,60,1.2)(120,72,1.2)(60,96,1.0)
Row y 60-110: (180,88,1.4)(230,110,1.0)(300,78,1.6)(345,100,1.1)(420,86,1.3)(470,120,1.0)(520,96,1.2)(700,110,1.4)(760,140,1.1)(30,150,1.3)(90,180,1.1)...

I'll write out a decent list with random-ish values and add opacity/delay attributes. Use CSS classes s1,s2,s3 for durations and delays, with inline style for delay.

Simpler: define keyframes "tw1" 3s, "tw2" 4.5s, "tw3" 6s, "tw4" 2.2s and assign via class. Delays: use style="animation-delay: -1.3s" etc. Negative delays ensure they don't all sync.

Let me write the final code now. I'll be careful with the gradient references.

Full SVG plan:

1. Sky rect with url(#sky).
2. Nebula subtle radial ellipse? maybe a big soft radial in #6A3E7A opacity .15 at (300,250) r 250. Adds depth.
3. Stars group (twinkling circles) + sparkle crosses.
4. Moon glow + moon disc + craters + a soft halo ring.
5. Shooting star group (SMIL).
6. Distant mountains: two paths.
7. Far hill with tiny trees.
8. Mid hill.
9. Foreground hill (big).
10. Trees on foreground (left cluster, right cluster).
11. Grass tufts + small flowers.
12. Fox (group): tail (swaying), body, haunch, chest, legs, head, ears, eye, nose, highlights.
13. Maybe foreground silhouette bushes at bottom corners.

Let me write coordinates for hills.

Far mountains (behind): path from x=0..800 around y=330-420:
M -20 400 C 60 340, 120 350, 180 300 C 230 260, 280 300, 340 330 ... this is getting. Let me do two simple layered mountains:

Range A (farthest, color #3A2A5E):
M 0 420 L 60 372 L 110 396 L 175 330 L 235 392 L 300 350 L 360 400 L 430 344 L 500 396 L 560 356 L 640 402 L 720 350 L 800 396 L 800 600 L 0 600 Z

Hmm but the moon at (620,140) is above; fine.

Range B (mid, color #2C2150):
M 0 460 C 80 420, 150 440, 220 412 C 300 382, 360 420, 430 400 C 520 375, 600 415, 700 396 C 760 385, 790 398, 800 394 L 800 600 L 0 600 Z

Then far hill with tree line (color #241C44) with small pines on the crest around y=400-430.

Pines small: triangles at various x along the ridge. Ridge of range B around x=220 is y≈412 etc. I'll place pines along a gentle ridge line I define.

Mid hill (foreground hill big) crest:
M 0 600 L 0 500 C 90 470, 170 455, 260 452 C 360 448, 430 462, 520 470 C 620 480, 700 465, 800 440 L 800 600 Z
Fox at x≈300 sits on crest at y≈450. Good.

Actually let me make the fox sit on a small mound so contact looks right. Fox baseline y=452 at x=300: crest at x=300 is ~449. Fine, close enough; I'll put fox bottom at 452 and adjust crest slightly: at x=260-360 the crest ~450. Good.

Trees on foreground hill: left side pines at x=70-140, base y ~ 470ish; right side at x=690-760, base y ~ 455.

Pine tree shape (silhouette): a series of triangles. I'll create a reusable <g id="pine"> in defs and <use> it. Use <use> with transforms — that's fine, it's hand-written shapes (defs + use is standard SVG, not external reference). Should be acceptable: "no external references" means no external files. <use> internal is fine.

Define pine in defs:
```
<g id="pine">
  <rect x="-4" y="-6" width="8" height="16" fill="#0D1428"/>
  <path d="M0,-96 L22,-52 L12,-52 L28,-20 L8,-20 L8,0 L-8,0 L-8,-20 L-28,-20 L-12,-52 L-22,-52 Z" fill="#0D1428"/>
</g>
```
Hmm simplify: three stacked triangles + trunk:
```
<g id="pine">
 <path d="M0 -100 L 24 -50 L 14 -50 L 32 -14 L 8 -14 L 8 4 L -8 4 L -8 -14 L -32 -14 L -14 -50 L -24 -50 Z" fill="#0C1326"/>
</g>
```
That's a classic pine zigzag. Good.

Also a rounded shrub.

Grass tufts: small paths stroke color #24406B? Foreground hill is dark navy #121A30; grass tufts slightly lighter #1E2C4A.

Flowers: tiny circles in pale blue/white with a glow, at a few spots, with sway animation.

Now the fox in detail. Let me finalize positions.

Fox overall scale: sitting fox, height ~ from ear tip 256 to ground 452 = 196 px. Reasonable.

Layers (back to front):
a) Far ear (darker orange #C4702F): M 330 300 L 344 258 L 366 296 Z — but the near ear should be drawn after head. Order: far ear first (behind head), then head, then near ear, then details.

Hmm but far ear at x 330-366 while head spans 332-434. The far ear tip at (344,258). OK.

b) Tail (behind body) — but tail is in front of body? The tail sweeps around the front/side. In profile facing right, tail comes from behind (left) and can be drawn behind body. Draw tail first (behind body) then body. But my tail sweeps left and up to (196,328) which is behind the haunch (haunch center ~300,408 r 42) — tail x 160-280 doesn't overlap haunch much except near base. Fine.

Order: tail group → haunch → body → legs → chest → head → ears → face details.

Wait far ear must be behind head but in front of nothing else—fine, draw before head.

Let me define fox body shapes:

Tail group (with SMIL sway):
```
<g>
  <animateTransform attributeName="transform" type="rotate" values="-2.5 272 440; 3 272 440; -2.5 272 440" keyTimes="0;0.5;1" dur="5.5s" repeatCount="indefinite" calcMode="spline" keySplines="0.4 0 0.6 1; 0.4 0 0.6 1"/>
  <path d="M280 446 C240 448 200 434 180 410 C162 388 160 352 196 328 C186 344 186 366 198 380 C212 396 240 404 272 414 Z" fill="url(#tailGrad)"/>
  <path d="M197 318 C209 322 213 338 209 351 C204 366 193 377 181 381 C174 369 173 352 180 339 C185 329 191 322 197 318 Z" fill="#F7E9D2"/>
</g>
```
Wait: the tail must be attached to the body at (280,446)/(272,414) and the body haunch is around x 265-330. But the body is drawn after the tail so the tail's base is hidden behind the haunch. Good.

Hmm, but the tail sweeping left and up with a big gap from the body looks detached — the tail tip at (196,328) and body at x≥262. The tail path outer edge from (280,446) to (180,410): that region x 180-280 is visible, forming a crescent that lies along the ground? The crescent's "inner" edge goes from (198,380) to (272,414), so the tail's thickness near x=240 is between outer edge (~y 425) and inner (~y 400): thickness 25px. The tail lies horizontally-ish to the left of the fox at ground level, tip curling up. That's a plausible resting tail. Good.

Haunch (rear leg/thigh): ellipse cx=296 cy=408 rx=40 ry=44 fill url(#foxBody)? Use a path/ellipse. Actually sitting fox's thigh bulges. Use ellipse with gradient.

Also a hint of the hind leg down to a foot: path M 268 404 C 262 424, 262 440, 268 448 L 300 448 C 306 440, 308 420, 300 404 Z? Might complicate. Simpler: ellipse haunch + a foot shape at bottom left:
foot: path M 258 442 C 258 434, 268 430, 282 430 C 296 430, 306 434, 306 442 C 306 448, 300 452, 282 452 C 266 452, 258 448, 258 442 Z fill darker orange #D2702F (paws darker). Actually fox paws are black! Fox legs/paws are black. Yes — fox has black legs and paws, white chest. So the front legs should be dark #2B2130 rather than cream. That's more recognizable and authentic.

Red fox: rusty body, white chest/belly/tail-tip, black legs and paws, black ear backs, white muzzle.

So: legs dark charcoal #241C2C, chest white, muzzle white, tail tip white. 

Front legs (two, dark): 
leg1 (far, behind): path M 336 398 L 350 398 L 352 450 L 338 450 Z fill #2A2233
leg2 (near): path M 346 396 L 362 396 L 364 452 L 346 452 Z fill #1F1A29
Paws: rounded bottoms — add ellipses at (345,450) rx 11 ry 6 and (355,450) rx 11 ry 6.

Hind foot (black) at bottom left of haunch: ellipse cx=284 cy=444 rx=24 ry=10 fill #1F1A29. Hmm, but haunch ellipse bottom at 408+44=452 which is ground. Let me shift haunch up: cy=402, ry=42 → bottom 444. Then the hind paw ellipse at cy=444 overlapping bottom. Good.

Body (torso): path as earlier:
M 300 452 C 296 428, 292 404, 300 384 C 306 366, 320 352, 338 350 C 360 348, 372 366, 372 390 C 372 414, 368 434, 364 452 Z

So torso from x≈292 to 372, top at 350 (shoulders). Head above from 296 to 364 (head center ~360,325). Good — neck junction at (338,350)-(360,348).

Chest white: patch on the front (right side) of torso, following the chest curve:
M 348 352 C 362 356, 370 372, 370 390 C 370 414, 366 434, 362 452 L 338 452 C 346 428, 350 404, 348 382 C 347 368, 346 358, 348 352 Z fill #F7E9D2

Hmm the white chest should be visible from throat down. Let's make it narrower: left boundary x from 340 at bottom to 350 at top.

Path: M 350 350 C 364 356, 371 372, 371 390 C 371 416, 367 434, 363 452 L 341 452 C 349 426, 353 402, 351 380 C 350 366, 349 356, 350 350 Z

That covers the front strip of the torso, good.

Head: as defined:
M 332 330 C 330 310 344 296 362 296 C 380 296 392 308 394 322 C 412 326 428 334 434 342 C 437 347 433 354 425 354 C 414 354 404 351 396 348 C 392 358 380 364 366 362 C 348 360 334 348 332 330 Z

Head fill url(#foxHead) (orange gradient lighter at top).

Muzzle white: the lower muzzle region around (400-434, 330-354):
M 396 328 C 412 328 428 334 434 342 C 437 347 433 354 425 354 C 414 354 404 351 396 348 C 391 342 391 332 396 328 Z

Nose: at tip: path M 428 336 C 434 337 438 340 438 343 C 438 347 434 349 430 347 C 427 345 426 340 428 336 Z fill #1A1420. Hmm the snout tip is at (434,342) so nose around (432,340). Let's place nose ellipse-ish at (433,340) with the muzzle ending at 438. Let me extend muzzle to 440 and nose at 436.

Adjust head path end: ... C 414 326 430 334 437 342 C 440 347 436 355 428 355 C 416 355 405 351 396 348 ...
Muzzle white: M 398 328 C 414 328 431 335 437 342 C 440 347 436 355 428 355 C 416 355 405 351 396 348 C 391 341 392 332 398 328 Z
Nose: M 430 336 C 436 337 441 340 441 343 C 441 347 436 350 431 348 C 428 346 427 340 430 336 Z — that's a rounded blob at x 427-441. The muzzle ends at 440, so the nose pokes slightly past — good, fox nose.

Hmm the nose would overlap the muzzle tip region. Fine.

Eye: near eye at (376, 320). Draw as almond: path M 368 320 C 372 312 382 312 385 320 C 382 327 372 327 368 320 Z fill #1A1420, plus white glint circle cx=379 cy=317 r=1.8.

Cheek ruff (white/cream at cheek behind jaw) maybe: small cream shape under the eye region on the neck: 
M 344 336 C 348 350 358 358 370 360 C 362 362 350 356 346 346 Z — meh. Skip; chest white covers throat.

Ears: near ear: M 352 302 L 374 254 L 394 300 Z fill #E07A3C; inner: M 360 298 L 374 264 L 386 296 Z fill #8E4A55 (dark rose #A8566B?). Fox inner ear is black/dark. Use #3A2A38? Red fox ear backs are black with white edges; inner ear dark. Use inner fill #6E3A48 for a hint of pink, or dark #2E2233. I'll use #7A4257 muted.

Far ear: M 330 302 L 344 256 L 368 298 Z fill #C56C2E (darker). Slightly behind head.

Ear rim highlight on the moon-facing side (right side of near ear): stroke #FFD9A0 opacity .5 along the right edge: path M 374 254 L 394 300 stroke.

Head top rim light: path M 336 322 C 338 306 350 298 362 298 C 376 298 388 306 392 318 stroke #FFE0AE opacity .5 width 2.5 fill none.

Back rim light: along torso back (left side, but light from right... light from upper-right means the back's left side is shadowed; the lit edges are the top of the back and the right-facing surfaces). Hmm. The moon is up-right; the fox's right side (chest/front) faces the moon? The fox faces right, toward the moon. So its front (chest, muzzle) is lit, and the back is in shadow. So highlights on the muzzle top, head top, chest. Rim on the back edge would be less. I'll add subtle rim on head top and ear edges only, plus lighten the chest.

Tail highlight: top edge of tail crescent (facing up-right): stroke along outer edge partially, color #F0A45F.

Also fox's eyes: only one visible.

Add ground shadow ellipse under fox: ellipse cx=320 cy=452 rx=75 ry=10 fill #0A0F20 opacity .5.

OK, also the fox's body might look better with the head slightly overlapping the torso.

Let me also double check the ear positions relative to head: head top around y=296, x 332-394. Near ear from (352,302) to apex (374,254) to (394,300): sits on top-right of head. Far ear from (330,302) apex (344,256) to (368,298): top-left. Both visible, with far one slightly darker. Good, gives the classic fox look.

Since ears drawn after head for near ear; far ear drawn before head.

Now shooting star: place in sky, crossing from upper-left to lower-right? Classic: from upper-left toward lower-right. But moon is upper-right. Let's have it streak from top-right area down-left? I'll do it entering from the top-left region and heading to the middle-right, passing below the moon: start translate (-30, 70), end (560, 300). Trail extends back-left-up from head. The head at translate position. So at translate (560,300) the head is at (560,300) with trail going to (470,262). Fine, in sky above hills (hills start ~330 in places). At (560,300) still sky. OK.

Shooting star group:
```
<g>
  <animateTransform attributeName="transform" type="translate" values="-40,60; 0,0; 120,45; 420,150; 540,185" keyTimes="0;0.05;0.15;0.35;1" dur="4s" repeatCount="indefinite"/>
  <animate attributeName="opacity" values="0;0;1;1;0;0" keyTimes="0;0.04;0.07;0.2;0.33;1" dur="4s" repeatCount="indefinite"/>
  <path d="M0 0 L-104 -44 L-88 -32 L-10 5 Z" fill="url(#shootTrail)"/>
  <circle cx="0" cy="0" r="2.6" fill="#FFFFFF"/>
  <circle cx="0" cy="0" r="6" fill="#FFE9B8" opacity="0.5"/>
</g>
```
Hmm the shape: head at origin, trail to upper-left. Path M0,0 L-104,-44 (outer edge) L-88,-32 (inner) L-10,5 (near head) Z — need to make a tapered sliver: outer edge from (0,0) to (-104,-44); inner edge from (-88,-32) back to (-4,4). The width at far end between (-104,-44) and (-88,-32) is ~19px wide, which is wide at the far end — wrong, should taper to a point at far end and be widest near head. Let me do: M 0 0 L -108 -46 L -96 -30 L -8 4 Z: at the far end two points (-108,-46) and (-96,-30) - still a blunt end but the shape narrows toward head? No, near head the two points are (0,0) and (-8,4) → width ~5.7. Far end width ~19. So it's wide at far end, thin at head. I want thin far, thick near head.

Correct taper: outer edge from head (0,0) to far point (-110,-47); inner edge from far point to head region... that requires a single point at far end. So: M 0 0 L -110 -47 L -6 4 Z — a triangle: at head, from (0,0) to (-6,4) width ~7; apex at far. That gives a wedge widening toward the head. 

But a real meteor has the bright head and fading tail; a gradient fill from white at head to transparent at tail works: gradient along the tail direction. Define linearGradient id="shootTrail" x1="0" y1="0" x2="-110" y2="-47" gradientUnits="userSpaceOnUse": stops white .95 at 0, transparent at 1. But that gradient is in the group's local coords before the translate — gradientUnits userSpaceOnUse applies in the element's user space which includes the transform? The gradient coordinates are in the user space in effect when the gradient is referenced — which is the local coordinate system of the element referencing it (including its own transform? For an element with a transform, the user space for gradientUnits=userSpaceOnUse is the coordinate system in place at the time the gradient is referenced, i.e., the element's user space after its transform is applied? Per spec, the user coordinate system in place for the element referencing the gradient includes that element's transform? Hmm: gradients are resolved in the user space of the referencing element, which is after applying the element's own transform? No — the element's transform establishes a new user space for its children and for its own geometry. The gradient with userSpaceOnUse uses "the user coordinate system in place at the time when the gradient is referenced (i.e., the user coordinate system for the element referencing the gradient)". The element's own transform does affect its user space (the transform attribute establishes the new user space for the element and its content). Actually for `transform` on an element, the transform applies to the element's coordinate system — so gradient userSpaceOnUse coordinates are in the transformed space. Chrome does apply the element's transform to userSpaceOnUse gradients. I believe yes: the transform on an element applies to its user space, including gradients with userSpaceOnUse.

To be safe, use objectBoundingBox gradient with x1=1,y1=0,x2=0,y2=0.5 or similar — that's relative to the element's bbox, robust. Let me define:
<linearGradient id="shootTrail" x1="1" y1="0.5" x2="0" y2="0.5"> with gradientUnits default objectBoundingBox: stop0 white opacity .95, stop .25 white .5, stop 1 white 0. The bbox spans x from -110 to 0, y from -47 to 4. x1=1 is at the head side (x=0) → white at head fading to transparent at tail. Good, use objectBoundingBox with y1=y2=0.5.

Also add a soft wider glow: same triangle scaled? Add another path with bigger width and low opacity:
<path d="M0 0 L-110 -47 L-30 -8 Z" fill="url(#shootTrail)" opacity="0.4"/> — eh, skip; instead a blurred circle head via filter? Filters are allowed (feGaussianBlur) — that's still hand-written SVG. Using a filter for the moon glow would be nice, but radial gradient suffices.

I could add a filter for the shooting star glow: <filter id="glow"><feGaussianBlur stdDeviation="2.5"/></filter> applied to the streak copy. Let's include a blurred copy: <path d="M0 0 L-110 -47 L-6 4 Z" fill="#FFF6D8" opacity="0.6" filter="url(#softGlow)"/>. Nice.

Now CSS animations in the SVG:
```
<style>
  .tw1{animation:tw 3.2s ease-in-out infinite}
  ...
  @keyframes tw{0%,100%{opacity:.25}50%{opacity:1}}
</style>
```
For circles I need varying base opacity; the keyframe overrides. Fine.

Sparkle stars: 4-point star path with scale pulse using CSS transform: need transform-box and transform-origin; scale about center: transform-origin: center; transform-box: fill-box. Chrome supports fill-box. I'll use transform-box: fill-box; transform-origin: center. Then keyframes scale(0.6)→scale(1.15). Good. But if fill-box unsupported... Chrome supports it. I'll use SMIL animateTransform for those too for safety? SMIL with type="scale" scales about origin (0,0) — bad for a shape not at origin. Use CSS with fill-box. Chrome 100% supports transform-box: fill-box. OK.

Alternatively simpler: animate opacity only for sparkles too. Keep it simple and robust: twinkle opacity for all, plus a separate "pulse" group for sparkles using opacity animation. I'll include CSS scale for 3-4 sparkles using transform-box: fill-box — it's fine in modern Chrome.

Shooting star first appearance within 2 seconds: with keyTimes opacity 1 at 0.07*4s=0.28s and travels until 0.33*4=1.32s. Then invisible. Next cycle at 4.28s. Good: a shooting star every 4 seconds.

Hmm but requirement "a shooting star crossing the sky every 4 seconds (the first one within 2 seconds)" — satisfied.

Also add moon glow pulse: animate opacity of glow circle subtly (SMIL dur 6s).

Grass sway: a few tufts with CSS rotate animation (transform-origin bottom). Use transform-box: fill-box and transform-origin: 50% 100%. Or SMIL rotate with center in user coords. SMIL rotate values="-2 100 470; 2 100 470; -2 100 470" for a tuft at (100,470). Fine, but each tuft needs its own center — I'd need multiple animateTransform elements. Use CSS with transform-box: fill-box; transform-origin: 50% 100%; that's simplest, one class for all tufts.

Let's write the file. Also add a title/desc.

Star list generation — I'll write them out.

Let me write final coordinates for stars avoiding the moon glow region (x 450-780, y 0-300 roughly) — actually the moon glow region is a circle at (620,140) r=150; stars can still be near it but let's reduce. I'll place a few anyway for realism (stars visible near moon).

Let me now write out the whole SVG.

Also small detail: a few fireflies? No, it's night with moon; maybe subtle. Skip.

Let me write.

```svg
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 800 600" width="800" height="600">
  <title>Fox on a hill watching the moon</title>
  <defs>
    <linearGradient id="sky" x1="0" y1="0" x2="0" y2="1">
      <stop offset="0" stop-color="#070C24"/>
      <stop offset="0.35" stop-color="#14153F"/>
      <stop offset="0.62" stop-color="#2C1F52"/>
      <stop offset="0.82" stop-color="#4A2A5E"/>
      <stop offset="1" stop-color="#6A3A63"/>
    </linearGradient>
    ...
```

Horizon around y=430; sky occupies full rect.

Nebula: <ellipse cx="300" cy="330" rx="280" ry="130" fill="url(#neb)" opacity=".5"/> with radial gradient purple.

Milky way band: maybe a rotated soft ellipse with low opacity across the sky. Add:
<ellipse cx="260" cy="180" rx="330" ry="60" transform="rotate(-22 260 180)" fill="url(#neb2)" opacity="0.5"/>

Good.

Now stars — let me produce a list with class and style delay.

I'll write stars as:
<circle class="tw a" cx="40" cy="32" r="1.7"/>
with classes defining animation-duration and delay via CSS nth? Simpler: use three classes t1,t2,t3 with fixed durations and delays differing by class, plus inline style delays for variety. I'll just give each star a class from {t1,t2,t3,t4} where each class has different duration and delay. That's enough variety.

CSS:
.t1{animation:tw 3.1s ease-in-out infinite; animation-delay:-0.4s}
.t2{animation:tw 4.3s ease-in-out infinite; animation-delay:-1.7s}
.t3{animation:tw 5.7s ease-in-out infinite; animation-delay:-2.9s}
.t4{animation:tw 2.6s ease-in-out infinite; animation-delay:-0.9s}
.tw{animation-name:tw}

@keyframes tw{0%,100%{opacity:.22}50%{opacity:1}}

Good. Also some stars with a slight color variation (pale blue vs gold). Use fill="#EAF2FF" mostly and some "#FFE9B8".

Sparkles (4-point): path "M0 -6 L1.6 -1.6 L6 0 L1.6 1.6 L0 6 L-1.6 1.6 L-6 0 L-1.6 -1.6 Z" translated to positions.

Place sparkles at: (120,90), (330,60), (520,220)? (520,220) near moon glow - ok, (700,330), (240,150), (430,120).

Let's finalize and write out. I'll also add a subtle moon reflection/highlight on hill? skip.

Tree silhouettes: use <use href="#pine" transform="translate(x,y) scale(s)"/>. Note: use href (SVG2) works in Chrome; also add xlink:href for safety? Modern Chrome supports href. I'll use both? Using xlink:href requires the xmlns:xlink declaration. I'll just use href (Chrome supports since v49 for use? href supported in Chrome 49+ for <use>? SVG2 href on use is supported in Chrome 49+. Fine.)

Actually to be safe, I'll just draw trees inline rather than <use> — but that's a lot of repetition. <use> is fine.

Pines on the far hill (small, scale 0.25-0.4) at various x with the ridge y. Ridge of range B: I'll define a smooth ridge and place trees along it. Let me define the mid-hill ridge path:

M 0 470 C 90 430 160 448 230 420 C 300 392 360 430 430 410 C 510 388 590 424 690 404 C 750 392 785 400 800 396 L 800 600 L 0 600 Z

Tree bases along this: approximate y at x: 
x=90 → ~437; x=160→446? Let's just place: (60,442,s=.3),(95,436,.35),(130,444,.28),(180,438,.32),(250,404,.26),(285,398,.3),(340,422,.26),(430,410,.3),(470,404,.24),(520,400,.3),(560,410,.26),(640,410,.28),(700,404,.3),(745,398,.26)

Close enough visually since the trees sit on the hill edge.

Foreground pines: left cluster around x=60-130 on the near hill crest (y ~ 460ish at x=60? near hill: M 0 600 L 0 500 C 90 470 170 455 260 452 ... so at x=60, y≈474; at x=110, y≈462). Place big pine at (75, 478) scale 1.0 (height 100 → top at 378). Another at (120, 466) scale 0.7. Another small at (35,490) scale 0.6.

Right cluster: near hill at x=700 y≈470; x=740 y≈460. Place pine at (715, 476) scale 1.15 and (755,462) scale .8, and a shrub.

But careful: right side pines might collide with nothing. OK.

Also far-left trees on the mid hill etc.

Grass tufts on the near hill: several small arcs at y around 480-540, colors #1B2A44 and a few with tiny blue flowers (#8FD3E8 with glow).

Now writing the final SVG. Let me be thorough but efficient.

Also add: "grass" silhouette along the crest of the near hill for texture: a path with small bumps? I'll add small tufts individually.

Foreground bottom: darker vignette band at the very bottom: rect with gradient from transparent to #05081A at bottom, to ground the composition. Add rect y=560 h=40 fill url(#fog)? Or a full-screen vignette radial. I'll add a bottom gradient overlay rect with linearGradient transparent→#060A1C opacity .6, but that would darken the fox if it's at 452 (no, 452 < 560). OK.

Careful: the vignette rect must be placed before the fox? The fox is at y 250-452, vignette starts 560, so order doesn't matter much. Place vignette last, but then the bottom trees get darkened — that's intended.

Let me write everything now.

One more: the fox's head is at y 296-355 and the moon at (620,140) far up-right — the fox looking up-right. To convey "looking at the moon", tilt the head slightly up. Could rotate the head group by -10° about the neck point (348, 352) using SMIL? A static slight tilt is better: rotate the head group by -8 degrees around (345,350). Hmm, that would move the snout up. Let's apply transform="rotate(-8 345 350)" to the head group (ears, face). But then the ear far ear position shifts too — fine since they're in the group.

Actually a tilt up makes the snout point up-right toward the moon — good storytelling. But the nose and eye must look natural. -8° rotation: the head shape rotates; the muzzle goes up slightly. I'll do -6°.

But careful: the far ear is drawn before the head but must be in the same rotated group. I'll put the whole head group (far ear, head, muzzle, near ear, eye, nose, highlights) inside <g transform="rotate(-6 346 352)">.

Also the neck junction: head bottom at y~362, torso top at 350 — the head overlaps the torso. With rotation, still overlaps. Fine.

Additionally add a subtle eye highlight. And maybe a small "moon gaze" indication: no.

Let me also add a soft warm glow around the fox? Not needed.

Write it out.

For the fox body gradient: linearGradient id="foxBody" x1="0" y1="0" x2="1" y2="1" with stops #F0924A → #C8632A. And head gradient #F59B52 → #D97430. Tail gradient #EE8F45 → #C25F28.

Let me define:
<linearGradient id="foxCoat" x1="0.15" y1="0" x2="0.9" y2="1">
  <stop offset="0" stop-color="#F5A05A"/><stop offset="0.55" stop-color="#E27C36"/><stop offset="1" stop-color="#C05E28"/>
</linearGradient>

Tail: <linearGradient id="tailCoat" x1="0" y1="0" x2="1" y2="1"> #F09A4E → #C9642B.

Head: use foxCoat too but lighter: separate #headCoat #F7AC63 → #DE7A34.

Highlight rim strokes: #FFE1AE.

Now the ground shadow: ellipse cx=318 cy=450 rx=78 ry=11 fill="#070C1E" opacity="0.55".

Alright, write final code.

Also need to make sure the fox's bottom (452) aligns with hill crest. Near hill crest at x=300: path "C 90 470 170 455 260 452 C 360 448 430 462 520 470" — from x=260 (452) to x=520 (470) with control points 360,448 and 430,462. At x=300 the y ≈ ? Cubic from (260,452) with cp1(360,448) cp2(430,462) to (520,470). At t≈0.2: x = 260+3*0.2*0.64*100 + 3*0.04*0.8*170 + 0.008*260 = 260+38.4+16.3+2.1=316.8; y = 452*(0.512)+3*0.2*0.64*448(=172)+3*0.04*0.8*462(=44.4)+0.008*470=231.4+172+44.4+3.8=451.6. Good: at x≈317, y≈451.6. Fox feet at y=452 → right on the crest. 

Let me write the SVG file now, complete.

Also add a title/desc.

Star list generation — I'll write them out.
