Motion Frames Skill
Produce a single full-bleed motion composition. Inline CSS animations only — the page is the loop. Treat it as a poster frame that an exporter (HyperFrames, Lottie, etc.) can capture into a video.
Workflow
- Read the active DESIGN.md (injected above). Motion lives or dies on typography contrast — pick the most expressive serif / display token in the DS for the headline; the body / mono token labels everything else.
- Compose the canvas as a 16:9 hero with these layers, back to front:
- Stage — full-bleed
<main>. Off-white or DS-canvas background, very subtle dotted grid texture (CSS background,radial-gradientdots at 22–32px intervals). - Concentric rings — 2–3 SVG circles radiating from a focal point. Ultra-thin strokes (0.5–1px) in DS-foreground at low opacity. These rotate at different speeds (60s, 90s, 180s).
- Focal mark — a wireframe globe, a stylized object, or a typographic monogram drawn as inline SVG. ~28% of the canvas wide.
- Ring labels — short words / phonetic tokens placed around one of
the rings (e.g. "Hola · Bonjour · 你好 · नमस्ते"). They co-rotate with
the ring, with
<text>paths counter-rotated so the words stay upright. - Headline — bottom-left or center-bottom. Display serif, italic
accent on one word. Add a subtle
letterSpacing+ opacity reveal animation (@keyframes type-in). - Frame chrome — corner stamps (top-left lab tag, top-right brand or issue number) and a thin baseline rule. Static.
- Stage — full-bleed
- Animate with

- Write a single HTML document:
<!doctype html>through</html>, CSS inline.- All motion uses CSS — no scripts, so HyperFrames or any frame-grabber can capture it deterministically.

- Self-check:
- The composition still reads as a poster with motion paused at frame 0.
- At least 3 layers move at different speeds (depth comes from delta velocity, not parallax tricks).
- Accent appears once — usually the italic word in the headline.
Output contract
Emit between <artifact> tags:
<artifact identifier="motion-slug" type="text/html" title="Motion — Title">
<!doctype html>
<html>...</html>
</artifact>
One sentence before the artifact, nothing after.
