* fix(skills): storyboard review — bg-on-clip rule, slideshow output, parser parity guard Addresses the storyboard-angle review (jrusso1020): - M1 (invisible text): frame-worker.md (x3) + SKILL.md Step 5 (x3) now require a frame's full-bleed background on a class=clip layer, never the #root / data-composition-id element (the root is clip-gated to its scene window, so a background on it is not a dependable ground and dark text can land on the black host body). The assembler already paints frame.md's canvas onto index #root as the base ground; the per-frame clip rides on top. - B3 (slideshow truncates to slide 1): slideshow/SKILL.md gains an Output section (decks render via 'present'; 'render index.html' captures only the first composition; linear main-line MP4 export is deferred). - Parser drift: vendoredParity.test.ts guards the three vendored storyboard.mjs copies (byte-identical + parse-parity with @hyperframes/core). - skills-manifest.json regenerated for the edited SKILL.md files. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(cli): storyboard review — lint, validate help, snapshot, inspect, capture, render Addresses the CLI findings from the storyboard-angle review (jrusso1020): - lint (@hyperframes/lint): accept vendor-prefixed system-font keywords -apple-system / BlinkMacSystemFont so a system stack with a generic fallback no longer trips font_family_without_font_face (+ test). - help: list 'validate' under Project in 'hyperframes --help' (was runnable but undocumented). - snapshot: honor -o/--output (the flag did not exist; output was hardcoded to snapshots/). The dir is resolved once and threaded through capture + contact sheet + Gemini. - snapshot: split font status into loaded / error / unused with a one-line summary; only a real 'error' is reported as FAILED (an unrequested @font-face is 'unused', not a contradiction with 'loaded'). - inspect: suppress text_occluded across a scene-to-scene crossfade (occluder in a different data-composition-id mount while a scene is mid-fade); a same-scene or two-settled-scenes overlap still flags. - inspect: suppress content_overlap between in-flow siblings governed by the same flex/grid container (tight stacks / number lockups are layout slop). - capture: record source resolution (videoWidth/Height) in video-manifest.json alongside the DOM display box; consumers size off the source dims. - render: warn when the target carries a slideshow island (render captures only the first scene, so the MP4 is truncated to slide 1; use 'present').

hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio running at http://localhost:3002
npx hyperframes preview --port 4567
render
Render a composition to MP4:
npx hyperframes render ./my-composition.html -o output.mp4
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
Run rendering benchmarks:
npx hyperframes benchmark ./my-composition.html
