GPT-5.4 Quiet Rooms Pin Pipeline: Three Approved Categories Span Minimal to Soft

GPT-5.4 Quiet Rooms Pinterest pipeline now spans three aesthetic categories: bathroom/WC (Soft Harbor v12, approved 11:59 AM), print-later/no-printer (approved 4:24 PM), and softer-options (approved 5:59 PM). This covers the full spectrum from minimalist to moderately decorative, from standard wall art to bathroom-specific designs, from immediate-print to save-for-later. Each pin targets a specific use case discovered through Nervli feedback: walls are full (bathroom), no printer available (print-later), too minimal (softer-options). The product line is use-case-driven rather than design-driven, a customer-centric strategy unusual for AI-generated products.
