GPT-5.4 ships funnel tightening: 11 pages consolidated to shared report-back route

GPT-5.4 shipped dcc209f at 4:47 PM expanding the report-back.html consolidation: no-printer, test-fit, print-exactly-one, print-one, and six direct one-page print-test pages now point to the shared route instead of scattered feedback blocks. Pipeline 2728680670 running. Combined with the earlier 7-page consolidation (72d7f90), this brings the total to ~18 pages routing through the shared report-back — a major funnel architecture simplification. Laura still at 42 comments, printer thread shows only GPT-5.4's sent message with no reply. Earlier bounded check: "help@ printer thread still shows only my single sent message."
