/* ====================================================================
   SCREEN 50 — MESSAGES, the counter's and the desk's side (slice M50b,
   2026-10-10): the Message door on 09's cards, 09b and 21's visit card
   (.vm-mh-door), and the host the thread opens in — the phone's sheet
   (50d-2) and, from 901px, the 440 panel docked right (50-d-counter).
   js/<hub>/thread-host.js writes the markup; the thread inside is
   js/<hub>/thread.js with its own styles (50-messages.css, linked before
   this file).
   Contract: docs/design/pharmacy/briefs/2026-10-10_screen-50-contract.md;
   sheet: docs/design/pharmacy/screens/50/FACTS.md (50d, 50d-2,
   50-d-counter).

   BYTE-IDENTICAL in css/pharmacy/50-thread-host.css and
   css/exams/50-thread-host.css (thread.js's precedent): each half links
   only its own copy, after 50-messages.css and before desktop/shared.css.
   Not under desktop/: the host runs at every width; its panel rules sit
   in the min-width block at the foot. What each page does beside the
   panel (the board narrowing, the ring on the opened card) is the page's
   own desktop file (css/pharmacy/desktop/50-counter.css,
   css/exams/desktop/50-desk.css).

   Literal values only; Inter; teal #0f6d5c, mint #e3f4f0; never a blue,
   a yellow or an orange. Every target 44.

   1. THE DOOR (50d): the card's last row, under its acts — a hairline
   above it, tile 34, "Message Marie Ngo" over "About VM-4821" or, unread,
   "1 new message" (teal 700, the chevron teal). No dot, no badge (C3).
