Sprite Animation Skill

Produce a single animated frame of an educational explainer — the kind you might screen-record into a vertical video. Pixel-art mascots, big year display, looping CSS animations, kinetic Japanese / English display type.

Workflow

  1. Read the active DESIGN.md (injected above). Pick the loudest serif token for the year, a sturdy sans for headlines, and a mono token for timeline / index labels.
  2. Pick the topic from the brief (e.g. "Nintendo · 1889 — Hanafuda"). You always need: a year, a one-line headline, an animated subject (a pixel sprite — character, object, or icon), and a short caption.
  3. Stage — full-bleed cream / off-white background (#f5efe2) with a subtle paper grain. Keep margins generous; this is one beat of a video.
  4. Top bar — small mono row:
    • Left: title slug ("名次の/番組" or "EP. 01 / NINTENDO")
    • Right: progress dots ("01 / 12") and a "REC" stamp
  5. Subject animations — at least three independent looping animations on the page:
    • Big year: the headline year (e.g. "1889年") fills the lower-left, in a serif display weight. It has a subtle vertical glitch / scanline animation (clip-path keyframes), and a 1-frame "pop" every loop.
    • Pixel sprite card: a 96×128 pixel-art card or character (use an inline SVG with crisp shape-rendering: crispEdges rectangles, or a box-shadow pixel grid). Subtle bobbing animation (±4px, 1.6s).
    • Kinetic kana: 1–2 Japanese / kanji characters that fade-and-slide in sync with the bob (e.g. "花" — hana — flower).
    • Tick ribbon: bottom of the stage, a tape/ribbon with year ticks (1889 · 1907 · 1949 · 1977 · 1985 · 2006 · 2017) sliding left at a slow constant speed.
  6. Caption block — small mono caption explaining the trivia: "Nintendo started as a Hanafuda playing-card maker in Kyoto, 1889. Mario didn't show up for another ninety-six years."
  7. Write a single HTML document:
    • <!doctype html> through </html>, CSS inline, no external JS.
    • All animations use @keyframes + animation: ... infinite.
    • Stage uses a fixed canvas ratio (e.g. 16:9 letterboxed) so the loop reads as a single frame from a video.
    • data-od-id on stage, year, sprite, caption, and tick ribbon.
  8. Self-check:
    • The page is one cohesive scene, not a collage. The eye lands on the year first, then the sprite, then the caption.
    • At least 3 independent looping animations are visible.
    • The color palette is restrained (cream + a single accent red + ink).
    • No external assets — all sprites are inline SVG or CSS.

Output contract

Emit between <artifact> tags:

<artifact identifier="sprite-anim-slug" type="text/html" title="Sprite animation — Title">
<!doctype html>
<html>...</html>
</artifact>

One sentence before the artifact, nothing after.
