Randomize video clips: top up the genre pool from the full catalog

The per-genre affine clip pool was only ~8-12 clips (GENRE_CLIPS ∪ tag matches), so the no-repeat bag recycled the same handful every 8 bars while ~220 of the 231 cached clips were never seen

Verified: headless: pool 61 clips, 59/60 draws distinct, 0 immediate repeats.

▶ Play it: Neon Fiscal Year → Benthic Patience → Silken Reentry — a constellation across three families — the path is the mix https://stellate.app/?genre=citypop&seed=6711&path=1530.6221,586.10667,1376.19565&xdur=0.056
