Undo/redo as time-travel over serializePatch(): loadPatch already restores
everything and rebuilds open panels, so undo is a 32-deep ring of snapshots.
- ungodlyMark(label) snapshots BEFORE a mutation (dedup identical, cap 32,
clears the redo future); ungodlyGesture(label) coalesces a drag burst
(same label within 800ms) into one entry; undo/redo loadPatch under `muted`.
- ~47 mark sites at every patch mutation: mood, zero enter/exit, dimension +
vibe load, route patch/unpatch, the beat panel (steps/groove/euclid/expr/
kit/mute/play), the arranger (grooves/clips/scale/euclid/follow/expr/p-lock),
and the mix (mute/solo/reset/level/trim/group). Boot restore is suppressed.
- ⌘Z undo · ⌘⇧Z redo, added before the letter shortcuts; every single-letter
key (p/c/o/w/z/t/b/g) now guards !metaKey && !ctrlKey — so ⌘Z no longer
toggles zen (the pre-existing quirk), while plain z still does.
- One ctxItem with a live depth count. Memory-only in v1 (reload clears it).
App scope only; nothing inside the Synth IIFE.
