CLAUDE.md's shell prose said the phone's header "controls shrink or stand down"; there is no header there now. The search box's section gains the modal and the four rules behind it, page-header gains the count as the last thing to yield, and the top-bar-fit section gains what happens below its own band. NOTES.md gets the three measured facts, dated: `contain: paint` is why a Web Awesome popup is clipped on Chrome 113 and why no tier here can reproduce it, the arithmetic that cost the page header its count at 320px, and the shared long-lived e2e app that makes an absolute coordinate a hidden assertion about background jobs.
