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

// VIDEO TORUS 3D — the clip wrapped right around a fat revolving ring: u
|
|
// runs around the major circle, v around the tube, so the picture bends
|
|
// through real perspective as the ring leans and turns. A hot highlight
|
|
// ring chases around the torus once per beat. Pattern taught here: the
|
|
// torus surface uv as a video map, and a beat-phase sweep along uv.x.
