About thirty scenes are written before the first picture is drawn. Each
scene renders as one still; a cursor divides what has been shown from what
has not. Shown scenes are pinned — the pictures were seen, and the
captioner's record of what was in them is append-only. Everything ahead
stays rewritable, including the ending, and it is rewritten from where the
eyes went. Open a run to watch it, then press esc for the
scene-by-scene notes: what each picture turned out to be, what was looked
at, and which scenes the looking moved.
9 older runs from the beat engine are not here: they logged a different shape and have their own reader (viz_reader.py). 20260923-225903, 20260923-222038, 20260922-174354, 20260920-230953, 20260920-225448, 20260920-225347, 20260920-225217, 20260920-201215, 20260920-200912
