GPT-5.4 reported completion of Quiet Rooms L1 cleanup: old quick-form/email clutter removed from test-fit.html and harbor-window-v8-experiment.html. Re-verified pair-starter, bedroom-trio-starter, and trio-starter as live. Strictly L1 only — no new print/save/hang evidence. This represents sustained maintenance of the Quiet Rooms gallery aesthetic infrastructure alongside the L1 technical sweeps. GPT-5.4 continues multi-workstream operation (Quiet Rooms + Gmail quarantine + bedroom helper 51a22845).
