canvas.drawElementImage is an unlaunched Dev/Canary-only Blink feature
(~151+). The CLI's pinned CHROME_VERSION fallback was still 131.0.6778.85 —
a puppeteer 24→25.2.1 bump that pinned it to Chrome Dev 151.0.7912.0 was
written on 2026-06-29 but never merged (orphaned local commit, no PR). Any
render on that pin, or on the shared puppeteer-cache binary, or on system
Chrome (Stable, no drawElementImage at all) got a canvas.getContext("2d")
missing the method and crashed mid-capture with "ctx.drawElementImage is
not a function" instead of falling back (HF#2060).
Three changes:
- Bump puppeteer/puppeteer-core to ^25.2.1 across every package that
depends on it, and CHROME_VERSION to 152.0.7928.2 (today's Dev channel;
confirmed via direct probe to implement drawElementImage, unlike 131).
- `ensureBrowser({ preferManagedChrome: true })`, always used by `render`:
resolve straight to our pinned/cached build, skipping both the shared
puppeteer-cache preference and system Chrome. Rendering shouldn't depend
on whatever arbitrary Chrome a machine happens to have — that's exactly
how this regressed (any Mac with Chrome.app installed bypassed the CLI's
pin entirely).
- A runtime capability probe in the engine, right before any other
drawElement work: if `drawElementImage` isn't a function on the injected
canvas, route to the existing screenshot-fallback gate instead of
crashing. This is the real backstop — it protects every resolution path
(env override, stale cache entry, a future Chrome regression), not just
the ones `preferManagedChrome` reaches.
Verified end-to-end: rendering against chrome-headless-shell 131 (confirmed
to lack drawElementImage) now falls back cleanly and produces a valid MP4
instead of crashing; rendering against a capable build still engages
drawElement normally. 922 engine tests + 1373 CLI tests pass.
Fixes #2060.
@hyperframes/studio
Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.

- Live preview — see changes in real time as you edit
- Composition inspector — view and modify element properties
Development
The studio is embedded in the hyperframes preview command. To develop the studio UI itself:
cd packages/studio
bun run dev # Start Vite dev server
bun run build # Build for production
bun run typecheck # Type-check
