name: Windows render verification

# Manually triggered smoke test that renders a HyperFrames composition on a
# real Windows runner. Proves the PR #336 `where ffmpeg` fix actually works
# end-to-end: FFmpeg is discovered natively on Windows, Chrome is installed
# and launched, frames are captured, and an MP4 is produced — without Docker
# or WSL.
