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

// OCTA RING — ten small video octahedra strung on a slow carousel, every
|
|
// stone tumbling on its own hashed axis and bobbing on a detuned sine, so
|
|
// the ring glitters with staggered flashes of the clip. Pattern taught
|
|
// here: leaving fx_axis at the engine default (a hashed per-instance axis)
|
|
// while the doc owns only the carousel placement.
