The certified functional matrix is Chromium and Firefox from Playwright 1.61.1 on desktop Linux. Chromium image goldens are regression tests, not cross-engine or Blender parity tests. WebKit, Safari-branded builds, and mobile are not certified.

The main thread requires module Worker, crypto.randomUUID, and Canvas 2D. The worker requires OffscreenCanvas, a 2D context, cropped createImageBitmap, and ImageBitmap.close; there is no fallback. Named capability errors identify missing features.

Cross-origin isolation enables an optional SharedArrayBuffer pointer lane per view. Without it, normal postMessage transport remains functional. Limits include 16 attached views, DPR 4, 8192 logical pixels per dimension, 16,777,216 device pixels per view, 67,108,864 device pixels across all views, and history 1,000.
