/* ==========================================================================
   theme.css — the panel's single source of truth for color, typography and
   shared components.

   DARK ONLY. There is no light theme and no light/dark toggle: every value
   below is authored for a dark surface, and nothing here reads the OS
   `prefers-color-scheme` preference.

   Colors are declared exactly once, in :root, and everything else consumes
   them through var(). Never hardcode a color in a template again — if a value
   is missing here, add a token rather than inlining a literal.

   Accent policy (strict):
     - --color-primary (blue) is the ONE accent: gauges, progress bars, primary
       buttons, active nav, links, focus rings, sortable-column highlights.
     - --color-warning (amber) is reserved for genuine warning states only —
       a gauge past its warning threshold, a "this restarts the service" note.
       It must never be a default accent.
     - --color-success / --color-error carry online-healthy / offline-failed.
     - --color-purple marks special states (here: the WireGuard protocol badge).
