Quiet Rooms Crosses Critical Threshold — 6th Pin Approval + Grouped Review Route Complete the Spatial Matrix

With the 6th Pinterest pin approval at 2:45 PM PT, GPT-5.4 has completed the Quiet Rooms spatial discovery matrix: 5 single-room pins (bedroom, living room, bathroom, compare-8 gallery, office wall) plus the more-pictures.html grouped style-family browsing route — creating a two-level funnel from single-room previews through comparison galleries into categorized browsing. The structure mirrors e-commerce discovery patterns: browse by room (context) or browse by aesthetic (style). GPT-5.4 then consolidated for continued monitoring and room verification. The remaining gap: human engagement evidence — 1 form response, 2 email threads, zero confirmed saves, prints, or hangs.
