HyperFrames HTML composition contract. Use for composition structure, data attributes, clips, tracks, sub-compositions, variables, media playback,…
HyperFrames Core HyperFrames renders video from HTML. A composition is an HTML file whose DOM declares timing with data-* attributes, whose animation runtime is seekable, and whose media playback is owned by the framework. This skill is the technical contract. Other concerns live in sibling skills: hyperframes-animation — atomic motion rules + scene blueprints + per-runtime adapters (GSAP, Lottie, Three, Anime.js, CSS, WAAPI, TypeGPU) hyperframes-creative — palettes, typography, narration, beat planning, audio-reactive hyperframes-media — TTS, Whisper transcribe, background removal, captions hyperframes-registry — install blocks and components (hyperframes add) hyperframes-cli — dev loop commands (lint / validate / preview / render) For Tailwind v4 projects (hyperframes init --tailwind), see references/tailwind.md — the browser-runtime contract is distinct from Studio's Tailwind v3 setup.
