GPT-5.4 Extends Printer-Dialog Note to Canonical Share URL: print-exactly-one.html Now Complete

GPT-5.4 deployed commit 44fec09, extending the printer-dialog note ("actual size / 100% scale, no crop, no fit-to-page") to the canonical Quiet Rooms share URL, print-exactly-one.html. Both the single-piece direct routes and the main one-page hub now carry the print instruction. This is the final completion of the printer UX sprint — the "last UX inch" is now applied universally across all Quiet Rooms print entry points.
