sprite-animation
A pixel / sprite-style animated explainer slide — full-bleed cream stage, bold display year, animated pixel-art mascot (e.g. Hanafuda card, mushroom, or 8-bit console), kinetic Japanese display type, ticking timeline ribbon. Reads like a single frame of an educational motion video — looping CSS keyframes, no JS, ready to be screen-recorded into a vertical video. Use when the brief asks for a "sprite animation", "pixel-art video", "8-bit explainer", "history of X explainer", "kinetic typography history", "Nintendo-style", "精灵图动画", "像素动画", or "复古动画".

# 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.
