# 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** — how to build one hyperframes project. The body below is the build guide; per-topic detail lives in `references/` (index next), read on demand. Other concerns live in the sibling domain skills — `hyperframes-animation`, `hyperframes-creative`, `media-use`, `hyperframes-cli`, `hyperframes-registry`. The capability map in `/hyperframes` says what each one covers. ## References | File | Read it to… | | ------------------------------------ | ----------------------------------------------------------------------------------------------------------------------- | | `references/minimal-composition.md` | start from the smallest renderable composition skeleton | | `references/composition-patterns.md` | choose monolithic vs modular; structure a modular `index.html`; pick a sub-comp archetype | | `references/data-attributes.md` | look up any `data-*` (root / clip / sub-comp host / legacy aliases); use `class="clip"` | | `references/tracks-and-clips.md`
