* feat(check): opt-in --layout proseCoverageFloor for text_occluded Keep the default prose coverage floor at 0.15 for all callers, and allow stricter agents (e.g. Zephyr) to lower it via --layout "proseCoverageFloor=0.05" without changing other layout gates. Co-authored-by: Cursor <cursoragent@cursor.com> * style(check): collapse --layout comments and docs to one line Co-authored-by: Cursor <cursoragent@cursor.com> * fix(check): strict proseCoverageFloor parse + pin 0.07 floor tests Reject trailing-garbage fractions that Number.parseFloat would accept, and pin the existing ~0.07 coverage fixture for default vs floor=0.05 (atomic labels unchanged) plus a collectLayout forwarding assertion. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(check): share parseNumberStrict across layout and frame-check Sweep the sibling --frame-check tol parser (and caption fractions) onto the same strict Number() helper so trailing garbage cannot prefix-parse.

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. Run from the project directory; the positional
argument is the project directory (not a file), so render the project's
index.html directly, or point at a specific composition file with -c:
npx hyperframes render -o output.mp4
npx hyperframes render -c ./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
doctor
Check your environment for required dependencies (Chrome, FFmpeg, Node.js):
npx hyperframes doctor
browser
Manage the bundled Chrome/Chromium installation:
npx hyperframes browser
info
Print version and environment info:
npx hyperframes info
docs
Open the documentation in your browser:
npx hyperframes docs
upgrade
Check for updates and show upgrade instructions:
npx hyperframes upgrade
npx hyperframes upgrade --check --json # machine-readable for agents
