/* =====================================================================
   BANGBOWBING OS — CHAT app styles
   Lifted out of os/os.css byte-for-byte by the v3 scene phase (ledger item 33's
   css split, kept under the item 44-47 game frame) so phase-2 app workers edit
   disjoint files. Shell, the shared app kit, the emote/rarity tokens and the
   lightbox stay in os.css; this file owns Chat, its mod tools and the case-pull line.
   Linked from desktop.html AFTER os.css — same cascade order for ties.
