/* The `#chat-input` rules that lived here are gone (2026-08-10). They dressed the textarea for
   the old `.input-wrapper` pill — a bordered container that supplied the visible edge, so the
   field itself was `border:none; background:transparent`. That wrapper is not in the current
   markup, but the id was reused, and an id beats the `.chat-form textarea` class rule below:
   the composer rendered as invisible text on the page background. The rest of this section
   targets markup that no longer exists (`.chat-input-bar`, `.input-wrapper`, `.btn-send`,
   `.msg-row`, `.welcome-screen`); it is inert, unlike the id rules, which were not. */

/* ══ Clinical decision-support UI (added 2026-08-10) ══════════════════════
   The clinical views were originally written against a light palette and appended to a dark
   design system, so every rule below fought the shell above it: dark text on a dark page,
   light cards on a dark background, and no layout at all for `.main-area` — which left the chat
   column 235px tall in a black void. Rewritten 2026-08-10 to use the :root tokens.
   Anything that needs a specific colour (warnings, states) uses a dark-surface variant rather
   than the light one it had. ══════════════════════════════════════════════════════════════ */

/* Layout the clinical views actually need. `.app-page` is a 100vh flex column and `.app-body`
   is `overflow:hidden`, so the scrolling has to happen inside here or not at all. */
