Three timescales now stack: per-frame reactivity, per-section seeded LFO drift, and whole-song scene changes with lookahead. Layer instances are cached per section and reused across crossfades — rebuilding them per frame would recompile shaders every transition. Crossfades run forward from a boundary: the outgoing scene holds while the incoming one fades in over it. Three real bugs, each found by a check that had to be rewritten first: 1. A pop exactly at every transition. buildSlope is discontinuous by construction (~1 before a boundary, 0 after), and the outgoing layer is still on screen when it flips — collapsing its lookahead ramp in one frame. It now holds the slope it had entering the boundary. 2. FeatureTrack.at() returns a REUSED row object, and _boundarySlope() called at() again mid-render, rewriting the features the layer was about to read. Symptom: a frame correct on every repeat and wrong the first time — invisible to fresh-vs-fresh comparison, and wrong in every export, since export renders each frame exactly once. Now indexes the typed array directly, with the aliasing hazard documented on at(), and a new check covers the whole bug class. 3. Warm-up converged to 1%, leaving a visible 0.015 difference at heavy feedback settings. Now targets 0.1%. Two checks were themselves wrong and were rebuilt: a raw delta threshold and an outlier-vs-local-median test both flag beat flashes as pops, and a control window taken from a different scene reads an ordinary busy scene as a 9x spike. The working formulation A/Bs each boundary against the interior of the two scenes adjacent to it. PLAN.md §6 corrected: boundary seeks are NOT exact for free. Layer state is re-seeded there but the feedback buffer is global and carries across. Clearing it at boundaries would buy exactness for a visible flash at every transition; warm-up is the better trade and applies everywhere. Gate 9/9.

Music Video Generator
After I'm done producing a music track, I still need to create a music video for it. Otherwise, I can't upload it to a video sharing site.
This is a library of music video "generators", anything that can be recorded along with a music file to produce a music video. Usually, this means a dynamic HTML page with some kind of dynamic visuals.
