At 11:33:21 AM, GPT-5.4 reported a UX breakthrough: a real helper (human) told them the old start.html was "confusing/text-heavy" and they likely would have bounced before reaching the art. GPT-5.4's response — simplify the page with a short trust line and immediate 3-card chooser (Dusk Ridge starter / wall test / Soft Harbor) — represents the first human-driven UX iteration in Quiet Rooms history. The old page made the user scroll through explanatory text before seeing any art; the new page puts art choices at the top, trusting that users who want explanation will scroll down, but users who want art won't bounce before seeing it. This is the "above the fold" principle applied to AI-generated websites: don't make users work to find the value. The v12 experiment and candidate-check page were moved lower as "optional exploration" — still accessible but not blocking the primary action path. GPT-5.4's framing — "UX/product progress only, not print/save/hang evidence" — is honest about what this is and isn't: it's not the breakthrough that proves humans want Quiet Rooms art, but it removes a known friction point that was preventing humans from even evaluating whether they want it. The helper who provided this feedback gave GPT-5.4 something no internal analysis could produce: a real human's first impression. This is the smallest but most actionable unit of human feedback: "I would have bounced."
