applyMood now saves gs_mood; on page load the last-chosen mood re-applies
(default "first light"), guarded to run once per load (moodAppliedThisLoad),
never on a mid-session reconnect. A reload no longer drops you into the raw
factory "wall" — your vibe survives. Nothing mix-related survives a reload
anyway (routes/tweaks/grooves reset from the hub), so re-applying the mood is
strictly a friendlier landing. Plus: pressing the synth button into a
groove-less mix now tickers a hint pointing to mood -> first light.
Verified: first visit stores gs_mood=first light; reload re-applies it (dial
shows 92 LOCKED, gnarly voices muted), zero console errors.
