# Validates the experimental fast-capture (drawElementImage) VIDEO path on a
# native amd64 Linux runner — where chrome-headless-shell's per-frame BeginFrame
# drives a real paint each frame, so drawElementImage's snapshot is fresh and
# video captures correctly. This is the one part of the feature that could not be
# validated locally (macOS has no BeginFrame; Docker-on-rosetta hung).
# See docs/fast-capture-limitations.md (Limitation 2).
#
# Manual trigger: Actions → "Fast-capture video validation" → Run workflow.
