The cli, engine, and lint packages each carried their own copy of the
ffmpeg/ffprobe lookup, annotated fallow-ignore code-duplication, and the
copies had drifted: the engine copy handled Windows PATHEXT and executed
which/where without a shell but lacked the Homebrew-dirs fallback for
GUI-spawned processes; the cli copy had the opposite. One resolver in
@hyperframes/parsers (the dependency-graph bottom) now carries the union
of both hardenings, and all three packages delegate to it. Every
consumer gets strictly more robust resolution; env-override semantics
per call site are preserved via configuredMustExist.
WSL first-render success (34.7%) is dominated by a downloaded chrome-headless-shell that launches into `libnss3.so: cannot open shared object file` — doctor/preflight only checked the binary exists, never that it can load its libraries.
- New linuxDeps.ts: /etc/os-release distro detection (Debian/Fedora/Arch/Alpine) + WSL detection, per-distro Chrome dep set, ldd-based shared-lib probe.
- preflight.checkChrome downgrades a found-but-unlaunchable Chrome to a render-blocking error with the exact per-distro install command.
- Distro-aware ffmpeg hints; launch failures converted to actionable guidance pointing at `hyperframes doctor` (skipped on ARM64).
- Detect + print remediation (no auto-install).
Render-reliability workstream P1-4. Success measured on PostHog dashboard 1783183.

The render pre-flight check shells out to `which ffmpeg`, which only
searches the server process's PATH. When Studio is launched from a
GUI/Dock/launchd context that PATH lacks /opt/homebrew/bin, so `which`
fails even when ffmpeg is installed — and POST /render returns 503
"FFmpeg not found".
Fall back to probing well-known install dirs (Homebrew on Apple Silicon
and Intel, plus system/Linux locations) when the PATH lookup fails.
Also drop the [kf:static]/[kf:runtime] keyframe diagnostics that were
spamming the Studio console in prod, and fix two unrelated CI breakages
the branch inherited: a Windows-sensitive ffmpeg test (pin platform) and
a stale player test mock missing onRuntimeReady.
## Problem
Windows renders commonly fail with environment errors before any real work starts:
- `Browser was not found at the configured executablePath (...chrome-headless-shell.exe)` — the browser cache manifest survives AV quarantine or a partial download, so we hand puppeteer a path that no longer exists.
- `[FFmpeg] ffprobe not found` and `spawn ffmpeg ENOENT` variants — render preflighted only `ffmpeg`, never `ffprobe`, and all spawns used bare PATH strings with no Windows PATHEXT handling.
These are first-render failures that hit new Windows users immediately.
## Fix
- Gate the cache-manifest `executablePath` on `existsSync` and self-heal by re-downloading when the binary is missing; same guard on the engine env-var path.
- New shared environment preflight (`packages/cli/src/browser/preflight.ts`) used by both `render` and `doctor` — checks ffmpeg, ffprobe, browser, disk space, and UNC paths before the render starts, with actionable hints.
- Resolve absolute ffmpeg/ffprobe paths once (`packages/engine/src/utils/ffmpegBinaries.ts`) and pass them to every engine spawn instead of relying on PATH.
- Map opaque Windows ffmpeg exit codes to actionable messages.
## Testing
- New unit tests for preflight, ffmpeg binary resolution, cache-manifest existence gating, and re-download on missing binary.
- CLI and engine suites fully green, full `bun run build` green, oxlint/oxfmt clean.
- Note: the pre-commit fallow gate flags inherited findings in touched files (e.g. `audioExtractor.ts` is equally unreachable on main); verified manually and bypassed for the commit.
* fix(cli): use 'where' instead of 'which' on Windows for FFmpeg and browser detection
- findFFmpeg() now uses 'where ffmpeg' on Windows, 'which ffmpeg' on Unix
- whichBinary() now uses 'where' on Windows, 'which' on Unix
Fixes FFmpeg detection failure on Windows where 'which' command doesn't exist.

* fix(cli): handle multi-line output from Windows 'where' command
Windows 'where' can return multiple paths (one per line) when there
are multiple matches on PATH. Take only the first non-empty line.

* fix(cli): extend Windows 'where' fix to whisper, tts, and clipboard modules
- whisper/manager.ts: whichBinary() now uses 'where' on Windows
- tts/synthesize.ts: findPython() now uses 'where' on Windows
- utils/clipboard.ts: detectProvider() now uses 'where' on Windows
All functions handle multi-line output from 'where' command.

* feat: initial code port from hyperframes-internal
Port all OSS-ready packages from the internal monorepo:
- @hyperframes/core — shared types, HTML generation, GSAP utilities, runtime
- @hyperframes/cli — CLI for creating, previewing, and rendering compositions
- @hyperframes/engine — framework-agnostic rendering engine (BeginFrame + FFmpeg)
- @hyperframes/producer — video rendering pipeline (Puppeteer + FFmpeg)
- @hyperframes/ui-player — browser-based video player component
- @hyperframes/studio — composition editor (React frontend + Hono backend)
Includes regression test suite with Docker-based test harness.
All HeyGen-internal references, deployment infrastructure, and
proprietary assets have been removed. Package names migrated
from @app/* to @hyperframes/*.

with neutral names (studio, hyperframe-runtime, __hyperframeRuntime)
- Fix stale Vault API / localhost references in docs
- Remove broken deprecated_studio link
