MiniMax M3.1 Flash

We need produce exactly one fenced code block containing complete file SVG since user asks draw SVG astronaut cat skateboarding on moon. Need make visually strong, self-contained, 1280x800 and adapt mobile 375 no scroll. Need maybe animated? Asked SVG, we can deliver full SVG with CSS animations if desired. Need be high quality composition of astronaut cat skateboarding on moon, recognizable cat face astronaut bubble helmet, lunar surface rocks craters Earth in star sky, skateboard and cat with motion. Need code only fenced svg. Must ensure no errors and meaningful initial. Could make SVG viewBox 0 0 1280 800, width 100% height 100% preserveAspectRatio xMidYMid meet role img. Inline gradients stars etc. We should plan visual composition.

Need output exactly one fenced code block ```svg complete SVG. No extra. Should have polished artwork. Could add subtle animation: stars twinkle, Earth glow, cat bobbing, moon dust, motion streaks, flag? Skateboarding cat on moon should look hilarious. Use vectors with cat orange tabby face inside helmet, body spacesuit, one paw up, legs angled on board. Moon surface lower third, Earth upper right, rocket far left maybe. Astronaut cat clearly. Need not overclutter.

Let's construct SVG 1280 800. Background deep navy gradient. Star field with circles and crosses. Large Earth in upper right maybe 220 radius partly? Position x1060 y140 radius 82, visible full. Nebula soft circles gradient filter glow maybe blur. Distant lunar horizon at y540. Crater shapes lower landscape. Main subject center x640 y420? Cat astronaut riding skateboard from left to right, board at y647? If board at 660, cat torso center x620 y395, helmet radius 123 center 610 y280. Ground starts y570 and board floats y660 with shadow below. Astronaut facing right. Need cat's face visible front 3/4 inside bubble helmet, ears, whiskers. Body white suit, backpack left behind, arms out to balance, legs bent. Skateboard angled slight up from left to right (rotate -7 about 640 660). Moon dust behind.

Detailed layering:
- background rect
- celestial stars
- Earth upper right with circle, continent paths clipped.
- distant moon mountains/craters at horizon y570.
- ground gradient.
- craters in lower plane elliptical shapes.
- flag maybe small far left at x140 y520 red/orange? Could distract; maybe lunar lander far left x130? Astronaut cat should focal. Earth more important.
- dust trail arcs from x270 y695 to x450 etc.
- skateboard group rotate -8 centered.
- cat astronaut group. Position relative.

We can make board x440-860 at y670. Wheels at x490 and 790 circles r23 y708. Deck curved path from M432 667 Q440 651 480 653 L830 634 Q858 633 865 650 Q860 670 828 674 L470 691 Q441 692 432 667. But rotate makes all align. Need feet contact deck. Better establish unrotated local subject group transform translate(0?) and rotated around center.
Maybe board extends x400 to 880 y664 with slight angled group rotate(-6 640 680). Wheels centers x500 and 790 y703. Cat feet local deck top around x525 y657 (rear) and x735 y651 (front). With rotation -6, y around 663? Fine.
Body torso centered x650 y435, from x560 y350 to x735 y520. Legs:
rear hip x575 y493, thigh to 570 y562, shin to 528 y642, boot toe from 498 to 562 at y651.
front hip x683 y502, thigh to 716 y555, shin to 737 y625, boot 705-777 y642.
Need suit with segmented joints, blue shadows, patches.
Torso white rounded shape M576 350 Q648 320 707 355 Q738 391 714 461 Q703 503 665 519 Q604 526 572 482 Q549 432 555 393Z. But backpack behind at x530.
Helmet around cat head center x636 y263 radius 132. Outer helmet dark rim and glass interior. Need cat ears extend inside helmet but can overlap rim? Helmet outer circle r137, glass inner r120. Cat head sits in center x645 y268. Ears around x568 y192 and x711 y186, triangular orange. Helmet ring around. White helmet outer. Cat face oval orange x579..715, y197..330, ears. Face stripes, eyes large green, nose pink, whiskers. Helmet glass highlights.
Helmet neck ring at y360.

Maybe build head:
- helmet back circle fill suit gradient stroke light; shadow on right
- glass circle fill #172c4e gradient, opacity .8, inner backdrop dark.
- helmet outer ring perhaps circle r135 stroke #f6f7fa width 16; side attachments.
- cat ears path M581 232 L573 160 Q574 148 587 154 L625 184 etc; fill orange stroke dark.
- Cat head path M583 215 Q630 180 693 215 Q723 248 704 300 Q687 340 642 344 Q593 337 578 301 Q562 255 583 215. orange tabby.
- inner ears pink.
- forehead stripes.
- eyes almond shapes at 610 270 and 674 266 with lime green iris, black pupils, white reflections.
- muzzle cream ellipses, nose triangle, mouth.
- whiskers strokes.
- glass reflection path overlay, clipped inside circle. use clipPath.

Spacesuit collar ring and body layering: helmet overlaps torso. Draw backpack first, torso then arms/legs then helmet last maybe arms behind torso. Body. Head centered x644.

Left arm (far) extends x581 y378 toward 498 y326, paw open fingers. Could make white sleeve path stroke width 48, with glove at end. Right arm extends x710 y380 to 798 y320, paw up. Balance. One paw waving. Better:
left arm path M574 387 Q542 374 516 345 L492 322 stroke suit width 48 round. Glove at (486,309), three little rounded fingers? Cat paw shape with toe pads.
right arm M710 379 Q754 373 782 332 L800 303 stroke width 48; glove around 805 293, fingers pointing up.
We can show right glove detached? Draw path stroke, glove shape.

Backpack x516 y360 width 84 height 140 rounded, gold panels and hoses to helmet.

Torso patches, NASA-like insignia? Could use paw emblem instead of text? Tiny circle with paw. chest control panel at x663 y407 maybe.

Legs white with joint rings gray, boot soles dark. The cat is on skateboard.

Moon: surface y570, main subject stands around y680, scale. Background horizon curve y565. Earth high right. Maybe light source upper left.

Could animate board floating? If group floating up/down moon low gravity, can animate subject translateY(-5) and shadow. Fine, motion dust drifts. But screenshot at 3 sec sees. CSS animations within SVG. Need no external fonts maybe text labels? The task just drawing; no text needed. We can add subtle "MOON? HANG LOOSE" not necessary, would spoil art. Better purely visual.

Need use filters drop shadows and glows; inline. Could use filter id shadow with feDropShadow, glow, blur. All okay.

Need adapt to 375 width: SVG width 100% height 100%, preserveAspectRatio means letterbox; 1280x800 -> at 375x maybe 234px tall centered. Requirement adapt gracefully down to 375 no horizontal scroll. ViewBox is 16:10; height 100% gives full maybe letterboxed. That's okay. Could width 100vw height 100vh. On mobile 375x800, preserveAspectRatio meet gives 375x234 and lots empty navy beyond (body background matching). Maybe better use aspect ratio preserve xMidYMid slice would crop sides at mobile, not ideal focal. meet leaves blank but composition still shown. User likely judged at 1280x800. Fine. We can maybe set svg width="100%" height="100%" style background. If viewport 375x800 with meet, vertical center. Good. Could perhaps use viewBox 0 0 1280 900? But target 1280x800 exact. Use 1280x800.

Need maybe create SVG with rich visual style. Let's design coordinates carefully.

Let's map layers:

Defs:
- bg linear gradient #050b1c to #172347 to #432d50 near lower
- glow radial etc
- earth gradient
- earth clip
- moon gradient
- suit gradient
- helmet gradient, visor gradient
- cat gradient
- shadow filter.
- clip circle for visor.
- dust blur.
- maybe star symbol.

Background rect.
Nebula ellipses using radialGradient and filter blur? opacity.
stars groups circles, cross stars.
Shooting star path upper left faint.
Earth group transform translate(1070 140) rotate(-12): outer glow circle r92 fill blue blur, sphere r72, continents clipped, cloud swirls, terminator. Could include orbit ring. Earth should upper right, x1080 y140. Moon scene can include Earth as Earth recognizable blue. Sphere with paths. Place land masses manually.
Maybe x1085 y155 r78. Atlantic etc.

Distant horizon:
path M0 570 Q130 535 265 566 Q420 520 585 560 Q760 525 940 560 Q1110 520 1280 552 L1280 800 H0Z fill moon gradient.
Ridge line thin.
Craters ellipses far.
Lunar lander? Might help scene but could distract. Add tiny lunar module at x150 y500? It's a cat skateboard scene, Earth and moon enough. Could add small flag left around x220 y440 with red-white flag? The flag's waving would animate; nice. But no need.

Main moon ground craters at x150 y690 etc.
Subject shadow ellipse x660 y723 rx230 ry35 fill dark .22 blur.
Dust trail left x310-470 around y680.

Board:
Group id rider transform maybe.
Order board behind legs but in front of dust. We can group all rider plus board. Board shadow separately.

Let's create board group rotate(-5 640 680):
deck path M424 664 C440 644 472 642 510 646 L839 646 C864 646 878 654 872 666 C867 677 845 681 820 681 L486 681 C455 681 432 677 424 664Z fill #1c2438 stroke #f7a43a width 6. Maybe upper stripe orange and underside cyan. Wheels x500 y709, x790 y709. Wheel circles dark outer, light hub. Board shadow under.
Need feet align: rear boot near 525 y648; front near 742 y646. Deck top around 646. Great.
Could include glow stripe under deck orange path.

Cat astronaut group, all rotate? Instead wrap entire rider in rotate(-5 640 680) so feet follow board. Then no separate board. Good. But helmet tilted also dynamic. Group transform rotate(-5 640 680).
Maybe order: board, legs, backpack, torso, arms, helmet. Board behind feet. Body coordinates.

Backpack:
rect x510 y355 width 91 h142 rx25 fill #c6ccda stroke dark 5; side dark panel x508; orange stripe. hose path M575 365 C545 330 545 290 568 278 stroke #798596 width 14 and highlights. Maybe back.
Torso suit:
path M580 353 C615 330 684 333 714 365 C735 393 725 445 704 486 C684 521 613 527 580 496 C552 470 545 414 560 382Z fill suit gradient stroke #dfe5ef width 5.
Need torso not cover neck ring.
chest panel x635 y390 w61 h40 rounded dark, with small colored dots and line.
badge x585 y404 circle.
belt y483.
Arms behind torso:
far left arm from 574 391 to 523 348 to 491 313. draw path fill none stroke #dce2ed width 48 round, dark outline maybe draw width 56 #5e6a80 then 48. Glove at 486 299. Paw with main rounded shape rotated. White. Finger slits dark.
right arm from 710 388 Q752 380 778 347 L802 305. outline and suit. Glove shape at 805,289. Draw main path M790 306 C779 293 783 276 793 270 L798 248 Q802 238 810 243 L815 263 L820 243 Q827 235 833 243 L831 267 L842 251 Q850 246 855 255 L845 281 C852 293 842 311 828 316Z fill white stroke. This glove is raised with fingers. Good.
Maybe right arm can be more horizontal.

Legs:
Hip under torso. Far leg from x604 y488 to 575 y551 to 536 y622; white stroke width 52 with outline 62. Joint ring ellipses. Boot at 504 634.
Near leg x677 y495 to 706 y555 to 734 y616; white stroke 54. Boot x709..774. Need be cat-like paws? Boots with paw toe impressions orange? It's astronaut cat, paws could be white gloves, suit. Maybe boots blue-gray with orange sole.
Detailed path for rear boot:
M513 620 Q501 636 501 650 Q522 664 563 655 L577 640 L551 614Z fill #55627b stroke dark; sole orange path.
Front boot:
M718 609 Q705 621 709 644 Q731 655 775 646 L781 633 L748 608Z.
Need feet touch deck at y648, yes.

Use shadow strokes for joints. Draw legs outline first #59657a width 58, then white gradient 48, then maybe ring at knees.
Since gradients in stroke okay.

Helmet:
neck ring ellipse at x646 y355 rx75 ry23 fill #d9dfe9 dark stroke.
helmet outer circle center646 y252 r139 fill suit stroke dark maybe.
Actually head at x646 y260. Outer circle extends y113 to391, overlaps torso/collar, nice. Need space helmet proportions.
Back outer maybe circle fill #ecf1f5, stroke #59667c 6.
Outer edge lower.
Visor circle center646 y252 r119 fill visor gradient. Cat ears within.
Rim circle r124 fill none stroke white opacity .7 width 4.
Helmet side knobs at x510 and 781 y265 small.
Cat head:
Ears behind head: left path M579 227 L573 171 Q573 157 587 163 L625 192Z orange dark stroke; right M670 190 L710 160 Q725 154 722 173 L716 231Z. Need right ear partly outside head but inside visor circle. Ears tops y154, visor inner top=133, good.
Head path M585 218 Q602 190 646 191 Q693 192 709 223 Q720 255 705 294 Q691 328 647 334 Q602 330 582 296 Q568 256 585 218Z. Orange.
Cream muzzle and cheeks. Tabby stripes on forehead and sides.
Eyes at 615 and 677 y260, green. Eye shape almond with white? Cats usually slit pupils; large green irises and vertical pupils. Draw ellipse rx16 ry20 fill green, black vertical ellipse 5x13. Add sparkle.
Nose triangle x640 285. Muzzle two cream ellipses 630/660 at 294. Mouth.
Whiskers on both sides but within visor? Whiskers can overlay glass and extend near edges.
Helmet reflection overlay clipped:
path M557 196 C590 141 669 119 728 159 C671 149 603 176 572 232Z fill white opacity .18.
small glare ellipse.
Glass blue arc.

Helmet foreground rim maybe circle stroke gradient? Outer already behind. Add right lower reflection. The cat head all within glass. Need draw outer white ring, visor, contents, then inner rim stroke maybe transparent. Outer ring visible.

Maybe cat ears cover? Fine.

Torso top starts y353, helmet outer bottom y391 covers upper torso. Collar draw behind helmet. Great.

Add "paw" patch on chest instead of NASA. Badge orange circle with paw shapes.
Cat suit maybe orange stripes on tail? Not visible.
Tail perhaps curl from backpack? Could add orange cat tail curling behind right? But astronaut suit no tail, can emerge from backpack? maybe not.

Helmet antenna? Small orange ear-like? no.

Main subject overall x474-856, head y113, bottom 732. Centered and dominates. Earth upper right. Negative left balancing.

Moon ground:
Dark shadow and crater rims. Use ellipses with strokes. lower x250 y714 huge crater, x1070 y668 etc. Use surface curved shapes.

Flag:
At x140-250 y430, a small pole tilted, red flag with paw print maybe. Flag could be red/white stylized, waving. Nice but could clutter. The cat theme maybe add tiny paw flag. Draw pole x190 y420 to190 y580, gold, flag path M190 422 Q225 405 259 423 Q230 442 192 432Z fill #ff684d, white paw. This helps story and balances Earth. But flag may appear behind horizon at y570. okay.
Maybe a small satellite/lander? skip.

Stars abundant.

Animation:
- twinkle stars opacity CSS @keyframes
- flag wave? transform-origin.
- earth rotates subtly? CSS transform rotate; transform-box fill-box maybe. Since group has transform attribute, CSS animation overriding complicated. Could animate clouds inside clipped group, but okay.
- astronaut bob: wrap group id rider with animation float 4s ease-in-out infinite; transform CSS on group may override transform attribute if wrapper. Use outer <g id="rider"> containing <g transform="rotate...">. Animate outer transform translateY(-5px), but transform-box? SVG CSS transform reliable. We can set animation: hover 4s ease-in-out infinite; @keyframes hover {0%,100%{transform:translateY(0)} 50%{transform:translateY(-8px)}}. For SVG transform presentation, translateY px works. Outer group no transform. inner rotation stays. Shadow static gives float.
- dust circles drift left.
- Earth clouds maybe subtle.
- Stars twinkle.

At 3 sec screenshot, still nice.

Need ensure accessibility title/desc. SVG no html. Fenced code block. The code might be long ~15k. That's okay. We should be precise. Let's formulate.

Let's consider perspective and readability. At 1280x800 subject height 620 (113-733), body 380 wide. cat helmet 280 diameter. Good. Moon surface starts 560, meaning lower body appears in front.

Background stars across. Maybe shooting star.

Lighting: highlights upper left, shadows lower right.

Defs:
radialGradient id=spaceGlow cx=.35 cy=.2 r=.8.
linearGradient id=sky.
radialGradient id=nebula.
filter softGlow, shadow, blur.
linearGradient suit x1 0 y1 0 x2 1 y2 1.
visor.
cat fur.
board deck.
moon.
earth.
clip paths.
symbol star maybe.
No external.

Filter region generous.

Potential issue opacity animation on star group? Fine.

Create star patterns manually 50 stars, varying. Use <g fill="#fff"> circles. Cross paths.

Earth:
<g transform="translate(1080 145) rotate(-15)">
 circle r=87 fill #5cc9ff opacity .12 filter glow
 circle r=70 fill earth gradient
 <g clip-path=url(#earthClip)> path continent fill...; cloud paths stroke...
 </g>
 circle r=70 fill none stroke #9bdfff opacity .6 width 2
 path highlight arc.
</g>
Earth clip coordinates center 0 r70 defined clipPath circle. The group transform applies clip? clipPath userSpaceOnUse default? define <clipPath id="earthClip"><circle cx="0" cy="0" r="70"/></clipPath>, within transformed group coordinate should follow transform yes.
Maybe path continents abstract but recognizable.
Orbit ring maybe ellipse rx96 ry30 rotate(-20) faint.

Moon surface gradient. Far ridgeline. Craters.
Flag should be before foreground subject. Moon ground then flag. Flag pole can overlap ground.

Foreground dust behind board.
Board within rider group. Need draw shadow separately before rider.
Subject group outer animation. Inside rotate group:
- board
- far arm perhaps
- backpack
- legs
- torso
- near arm
- collar
- helmet
Order: board, backpack, far arm, legs, torso, near arm? Arms should be behind torso, yes both before torso. But raised glove separate after sleeve.
Legs before torso. Helmet after.
Need board top visible around feet. Boots overlay deck.

Let's map exact paths.

Far (left) arm:
outline path d M574 393 Q548 382 526 355 L492 321 stroke #59667c width 58
suit path same width 46 gradient
elbow ring path maybe circle around 526 355 r24 fill none stroke #8994a8 width 5, but need transform to segment. Could draw small path M507 368 Q518 361 528 353.
Glove at 488 308:
<g transform="translate(484 307) rotate(-35)">

left ellipse cx610 cy259 rx18 ry22 fill #b9ef77 maybe stroke #322a35 width4. pupil path ellipse cx613 cy259 rx6 ry15 fill dark. right cx676.
Eye outlines cat upper.
Nose path M636 284 Q645 278 654 284 L645 294Z fill pink stroke.
mouth.
Whiskers lines #f8e6cf.
Stripes sides.

Helmet glass overlay: circle fill url(#glassSheen) opacity maybe. Def radial gradient glassSheen white .2 top left to transparent. Add path highlight.
Could make visor circle background radial #142b55, with star reflections? We already have star bg.

Helmet side modules:
left rect x493 y242 width22 height38 rx9 fill; right x776.
Tiny status green.

Helmet antenna? top small at x742 y120 maybe but cat ear enough.

Cat's paw glove details.

Flag:
pole with rounded, flag orange with white paw. Can animate flag gently with transform origin maybe CSS transform skew. Define <g id=flag ...>. Fine.

Dust: small circles around x350-470 y660, gray. animate drift.

Moon craters:
ellipses with dark fill and light rim. near x120 748 rx80 ry24, x1060 735 rx95 ry30, x920 610 rx45 ry13, etc.
Main shadow under rider x660 y716 rx225 ry30.

Could add curved motion lines behind skateboard in orange/cyan at x320 y625 etc.

Need no text maybe not.

Let's think if title and desc count as visible? no but accessible.

Output complete SVG, no XML declaration needed. Should include xmlns.

Potential requirement "draw me an SVG" maybe just code block. Exactly.

Let's maybe include an interactive small style? no.

Let's ensure syntax valid. All path commands okay. CSS @keyframes in <style> inside svg. No HTML. CSS transform on SVG g should work Chrome. Outer rider bob:
<style>
@keyframes bob { 0%,100% { transform: translateY(0);} 50% { transform: translateY(-7px);} }
#rider { animation: bob 4s ease-in-out infinite; transform-box: view-box; transform-origin: center; }
...
</style>
Actually transform-box: view-box means translation relative viewbox, still works. default transform-origin 0 0 irrelevant translation. Fine.
Stars: opacity animation groups.
Flag: maybe wave using <animateTransform> native SVG, but zero errors. Could use CSS keyframes with transform skewX but group transform attribute. Avoid.
Dust keyframes with transform translate(-30px). Use classes.
@keyframes twinkle {0%,100% {opacity:.25;}50%{opacity:1;}}
.star-a animation...
Different delay.
@keyframes drift {to {transform:translateX(-50px); opacity:0;}} initial circles positions. When transform CSS applies relative okay.

Use CSS prefers-reduced-motion maybe.

Potential screenshot at 3 sec sees horse? no.

Let's draft code fully. Need ensure Earth paths coherent. Earth at 1080, 140. Continents in local:
path M-50 -27 L-24 -48 L4 -46 L19 -29 L8 -13 L-6 -14 L-14 4 L-38 4Z (Americas?) and M22 -33 ... etc.
Clouds strokes.

Maybe draw small moon in upper? Earth enough.

Milky way nebula at left behind.

Let's formulate final SVG perhaps 25k. Need no extra text. Let's be artistic. We'll create around 300 lines.

Need maybe embed screen adaptation via style:
svg { width:100%; height:100%; display:block; background:#050a1c; }
body absent. fine.

One fenced code block only.

Let's check the moon surface starts at y560 and subject helmet top y110. Subject center x645. Earth upper right at 1085 138; flag upper left. Nice triangle composition.

Spacesuit patches:
circle at cx588 cy407 r16 fill #ff764f, paw white via small circles.
control panel at x633 y386 w62 h44 rx9 fill #27344d stroke; 3 dots and bar.
suit seam curves.

Flag paw shape use simple circles.

Earth glow.

We should perhaps include stars within visor? visor gradient is dark enough.

Add lunar horizon rim highlighted cyan.

Animation: group rider bob might float board 7 px; shadow remains. Good moon low gravity.

Let's create final now.
