+"""Build a labeled contact sheet of candidate slide frames for human curation.
+
+Usage: contact_sheet.py <video.mp4> <scene_times.txt> <out.jpg> [--cols 5] [--thumb 360]
+
+Reads timestamps (seconds, one per line), grabs a frame at each, lays them out in a
+grid labeled "<index> | <mm:ss>". Read the output image, then write the timestamps you
+want to KEEP (real content slides, not talking-head/transition frames) to a keep.txt,
+one per line. The index labels make it easy to call out which to drop.
