description: "All animation knowledge for HyperFrames — atomic motion rules, multi-phase scene blueprints, scene transitions, broader motion-design techniques, AND the seven runtime adapters (GSAP default, plus Lottie, Three.js, Anime.js, CSS keyframes, Web Animations API, TypeGPU). Use for any motion or animation task: pick 2-4 rules and compose, or load a blueprint, or look up runtime-specific API (e.g. GSAP eases / Lottie player / Three.js mixer). Also covers auditing an existing composition's choreography (animation map) and 24 named text-animation effects. HyperFrames-native: single paused timeline, seek-safe, deterministic."

HyperFrames Animation

All motion knowledge in one skill: **rules** (atomic recipes), **blueprints** (multi-phase scene templates), **transitions** (scene-to-scene), **techniques** (broader motion-design patterns), and **adapters** (per-runtime APIs).

For the composition contract (data attributes, sub-compositions, determinism) see `hyperframes-core`.

Default: compose atomic rules

Pick 2-4 rules from `rules-index.md`, glue them together with a single paused GSAP timeline, done. This is faster and produces less code than starting from a blueprint.

Load a blueprint when

• The scene matches an existing pre-designed multi-phase template (brand-reveal, social-proof, etc.) and reusing its phase pipeline saves real authoring time
• You want runnable ground-truth code for a complex 4-5 phase choreography

Blueprints live in `blueprints-index.md`. Each entry points to `blueprints/<id>.md` (recipe). Do not read it speculatively; load it when you've already decided you need scene-level orchestration.

Routing

Picking a runtime

• **GSAP** is the default for 95% of motion work — covers timeline orchestration, transforms, easing, stagger. All atomic rules in this skill are GSAP-based.
• **Lottie** when an asset has its own pre-baked timeline (typically After Effects exports).
• **Three.js** for 3D scenes, camera motion, shader-driven visuals.
• **Anime.js** for lightweight tweening when GSAP is overkill.
• **CSS** for simple repeated motifs, decoration, shimmer — no JavaScript animation cost.
• **WAAPI** for native browser keyframes without a GSAP dependency.
• **TypeGPU / WebGPU** for GPU-rendered canvases (particles, liquid glass, custom shaders).

Multiple runtimes can coexist in one composition. Each registers its instances on the runtime-specific global so HyperFrames can seek all of them in one pass.

Critical Constraints

**Prerequisite: `hyperframes-core` → Non-Negotiable Rules** (single paused timeline, `data-duration` governs length, no `Math.random` / `Date.now` / `performance.now`, no `repeat: -1`, no page-load `gsap.set` on later-scene clips, no `display` or raw `visibility` tweens, and no timeline construction inside `async` / `setTimeout` / `Promise`). GSAP `autoAlpha` and zero-duration visibility sets at explicit timeline boundaries remain all
