* fix(cli): bump @puppeteer/browsers to ^3.0.6 to fix render hang on node >=24.16 `hyperframes render` (and `browser ensure --force`) hangs forever during Chrome provisioning on Node >= 24.16 (repro'd on macOS arm64 / Node 26.5.0; fine on Node 22). Root cause is a transitive extractor bug, not our logic: @puppeteer/browsers@2.13.x install() -> extract-zip@2.0.1 -> yauzl@2.10.0 A classic-stream backpressure regression (nodejs/node#63487, works 24.15, breaks 24.16+) surfaces a latent fd-slicer destroy() bug in yauzl 2.x (yauzl#169). The inflate read stream stalls partway through the first entry large enough to cross the write highWaterMark (chrome-headless-shell's 1.86MB LICENSE.headless_shell, stalls at ~1.31MB), never emits `end`, so stream.pipeline never settles and extraction busy-spins. The half-extracted cache has no executable, so every later render re-enters "Cached binary missing -> re-download" and hangs again (puppeteer#14957). Fix: @puppeteer/browsers 3.0.2 dropped extract-zip/yauzl entirely (now uses modern-tar). Verified 3.0.6 extracts chrome-headless-shell cleanly under Node 26.5.0 and keeps the full API manager.ts uses (install, getInstalledBrowsers, Cache, computeExecutablePath, detectBrowserPlatform, Browser) with an identical on-disk cache layout. Cross-platform (the same .zip/yauzl path affected Linux + Windows too). Adds a regression guard asserting the pin stays on the extractor-free major (>= 3) and never reintroduces extract-zip/yauzl. Fixes #2103 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(cli): clarify extractor-guard wording — yauzl is an optional peer, not dropped entirely Review note on #2104: @puppeteer/browsers 3.0.6 keeps yauzl as an optional peer fallback (default extractor is modern-tar), so the regression-guard comment + it-text shouldn't say it was 'dropped entirely'. Test assertions (extract-zip + yauzl absent from `dependencies`) unchanged and correct.

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
