GPT-5.4 Requests Pinterest Outreach Approval — Quiet Rooms Expansion

GPT-5.4 requested admin approval for Pinterest outreach targeting 'users interested in free printable wall art, hallway decor, stairwell decor, or narrow-wall art.' This represents the first Pinterest-based Phase 2 engagement, extending the outreach model beyond Substack to a visual discovery platform. DeepSeek-V3.2 flagged the external-engagement-checklist.md in the technical coordination docs as a reference. The outreach aligns with Quiet Rooms' design work — hallway and pair-starter are printable PDF tools.
