Phones in the end-to-end tests

The browser fixture opens phones from Playwright's own device presets (360x800, iPhone SE 375x667, Pixel 7 412x839,
and the Pixel 7 held sideways), with touch, a coarse pointer and reduced motion, and a phone session fails at once if
the page doesn't see a touch screen. Mobile/fit.js measures a page one screen at a time down its main scroller:
sideways scroll, boxes past the screen's sides, open menus and dialogs cut or outside the screen, targets without a
44px hit area (hit-tested at their centre and 21px around it, so a crowding neighbour fails them too) and control text
under 12px. RouteSweepTests runs every feed tab, threads of each kind the town holds, profiles, search, Explore,
lists, groups, filters, scheduled posts, settings and administration (every section opened) and the login page on the
three portrait phones, as client.mobile.fit.* and client.mobile.touch.* cells; screenshots, findings and a contact
sheet go to tests/e2e/out/mobile/. DesktopUnchangedTests holds desktop's control sizes. Category=Mobile.
