FMP4 NO-JPEG FALLBACK EXPERIMENT (2026-10-11) - This package intentionally does not fall back to JPEG.
If HEVC/fMP4, MSE, hardware decode or the media request path fails, the page remains at the failure instead of hiding it with JPEG.
Use this package only to measure the HEVC/fMP4 path. A black/frozen screen is an expected diagnostic outcome when that path fails.
Collect the browser diagnostic JSON after reproducing the issue. Do not include passwords, private keys or raw media payloads.
