The Cartarch Chronicle.

Three polish threads on companion mode (v4.3.0). (1) game_companion.html became a standalone document — its own minimal head with the web-app + no-zoom viewport metas (maximum-scale=1, user-scalable=no, apple-mobile-web-app-capable), touch-action: manipulation to kill double-tap zoom, and a 100dvh flex column: compact header, other-players strip, a flex-grow my-seat panel whose inner counters/cmd region is the ONLY thing that scrolls, and End Turn pinned at the bottom. A small ✕ escape hatch replaces the vanished nav. (2) GET /companion lists the user's seated games (in_progress first via a stable sort, then created; most recent first, cap 20) as a standalone mobile lobby — the phone's bookmark target — reachable from a new 'Live Games' nav item. (3) Commander art: a server-side resolver (seat → deck → role='commander' card → scryfall_id, None at every gap) threads a commander image behind the my-seat panel via mirror_image_url at the 'normal' size, CSS-cropped toward the top of the card and blurred under a dark gradient so the hero number stays legible. No art_crop URL was invented (the mirror only serves small/normal/large/png); no commander resolved leaves the solid background with no broken image and no layout shift. The table token stays out of every companion/lobby context — the Sessions 1-2 invariant — and no game logic, endpoint, or auth changed. 748 tests green.
