Admin cb49b032df vjfx: 104 presets, engine hooks + hold stage, the videomesh engine, the audio picture, livecodable effects, and mp4 thumbnail sheets
Squashed from work; the fine-grained history is under tag archive/work-2026-08-26:
- vjfx: 104 new presets — the transition lane fills out and the screen family goes wide
- vjfx: three lanes land — engine hooks + hold stage, the videomesh engine, and the audio picture
- vj: the thumbnail pipeline becomes one honest machine, and effects go livecodable
- vj: thumbnails become mp4 — hardware-coded sheets at measured-4K cells, and the bake stops racing the GPU
- store: the ceremony dies — batch publish, one transaction, and the engine stops re-reading its own log
- store: the ceremony dies — batch publish, one transaction, and the engine stops re-reading its own log
- vj: the console grows real transports, and the deck stops lying about reverse
- vj: reverse earns a memory, and the effects stop aging
- fab: a 3D creation shell and the viewer built on it
