The calm front door. Zero is not a muted world (moods do that) — it's an EMPTY
one you build by hand, the same matrix started from nothing.
- enterZero(): snapshots the current patch → gs_prezero, then loadPatch({}) empties
the field; sets clientMatrix so the hub can't re-populate the cables; gs_mood="0 zero".
- exitZeroToMood(name): restores gs_prezero (the full factory) then applies the mood —
leaving zero brings the whole world back.
- First-visit choice card ("one world, three doors"): 🌱 start from zero · 🌅 first
light · ⛈ the full storm. Replaces the silent default-into-first-light; backdrop/esc =
first light. Returning users keep their last mood; a returning zero-user re-enters zero.
- Mood submenu gains "0 zero — build from nothing"; F11 toggles zero (KEY_ACTIONS).
Verified live (logged-in preview): card renders with 3 doors; "start from zero" empties
the field (56 factory cables cleared, snapshotted); F11 restores all 56 + first light
(92 BPM locked); returning-zero reload re-enters zero with no card; console clean.
The 7+7 calm slot UI is Z1. Not deployed yet (deploy is Z6, post-review).
