hyperframes-core
Provides the core contract for building renderable HyperFrames video compositions from HTML with timing attributes, tracks, sub-compositions, and deterministic rendering rules.
What it does
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.
Quality judgment
Excellent, well-scoped contract with a clear reference index, explicit non-negotiable rules with silent-failure rationale, and concrete validation steps. Lacks inline code examples (deferred to references), slightly weakening self-sufficiency, but the on-demand structure is appropriate for a large domain.
