/* Bloomberg-terminal aesthetic: dense, dark, monospace, keyboard-first.
   Tailwind v4 — design tokens live here in @theme (no tailwind.config.js).
   The booth runs on a fixed appliance display; we optimise for a dark room,
   glanceable status colour, and high information density over whitespace.

   Token vocabulary adopted from the "TRM" design system (Tracking & Race
   Management) — TOKENS ONLY: colours, type scale, spacing, radii, shadows.
   None of TRM's race-timing components are used. The existing `term-*` accents
   are aligned onto TRM's exact values so the whole booth UI inherits the TRM
   palette without renaming a single class. TRM's full vocabulary is also
   exposed as utilities (night-*, ink-*, paper-*, flag/amber/green/blue, the
   spacing/type/shadow scales) for new work.

   Offline appliance: NO webfont @import (no network at runtime). Goldplay (the
   TRM display face) is not self-hosted yet — display/heading text falls back to
   a clean sans stack; wire local Goldplay @font-face here if it's wanted. */

   The TRM tokens are good, but every screen hand-rolled inputs and

   and a button were visually indistinguishable. These classes give
   each control a real identity:
     - inputs read as RECESSED slots (lighter fill + inset shadow)
     - the primary button is FILLED (accent body, dark text) — the
       one obvious action; neutrals are filled grey, not bare outlines
     - explicit hover / active / focus / disabled states everywhere
   Use @apply so the classes compose with Tailwind utilities.

   LIGHT THEME
   The booth defaults to dark (dark room), but a user may prefer light; the
   choice is saved to their profile (users.theme) and applied on <html> as
   `.theme-light`. Every screen reads colour through the --color-term-* tokens,
   so re-pointing them here re-skins the whole app. The TRM "paper/ink" scale
   supplies the surfaces; accents are tuned a shade darker for contrast on white.
   A few component-layer values are literal hex (input borders, the inset
   "recessed" shadow, primary-button text) — those are overridden too so fields
   and buttons keep their affordance on a light background.
