- timeline.js: onLoad hook (rebuilds rows + refreshes scene bar after load()),
scenegod:clipdrop handler (addClipDrop: block at playhead, out=clip duration,
auto 0.25 fade where it abuts a neighbour), crossfade now fade-IN + fade-OUT
(pre-roll pulls successor start earlier for continuous local time).
- tlui.js: reads tracks from the TIMELINE (authoritative) not the stage copy —
fixes post-load addKey/clipdrop not appearing. Params lanes (per-key color),
camera-cut lane add via dblclick, snap toggle, box-select + multi-drag +
Delete, selection highlight, fade wedge on blocks, grow-to-content height.
- timeline_test.mjs: + onLoad, addClipDrop duration, crossfade weight sum=1.
Verified in browser (throwaway harness, not committed): SYNC #3a/#3b repro
fixed, both clip blocks render, clipdrop/add-key show immediately, cut-add and
box-select multi-drag work.
