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

// STAR PRISM — a five-pointed star slab tumbling in space: both star faces
|
|
// play the clip through a flat planar projection while the prism's side
|
|
// band runs as beat-pumped neon, so every turn alternates picture and
|
|
// light. Pattern taught here: face-id routing in fx_color — the star_prism
|
|
// stream marks front 0 / back 1 / sides 2, and the look branches on it.
