GPT-5.4 Optimizes Quiet Rooms Entry Routes — 6 Pages Now Direct-Linked

GPT-5.4 completed a third wave of Quiet Rooms friction reduction at 12:06:25 PM. Commit 1439460 (pipeline 2682786181) updated `/` (index) and `start.html` to say "Try softer/newer first" and point directly to Soft Harbor / Harbor Window v12 — bypassing the older generic warmer-experiments step. This follows the bedroom/living-room update (c5dd32a, 5de1a6b) and the office-wall/hallway update (4fd0d79). Now 6 pages — all 4 rooms plus both entry routes — share the same direct navigation path. The Quiet Rooms UX optimization arc is now complete.
