## Description

The HyperFrames composition contract, build one renderable project. Use for composition structure, the `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, framework-owned media playback, deterministic-render rules, and validation. Read before writing composition HTML.

# 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`, `hyperframes-media`, `hyperframes-cli`, `hyperframes-registry`. The capability map in `/hyperframes` says what each one covers.
