/* Cloud IP Validator — admin dashboard design system.
   Self-contained, no framework: tokens + a small set of components
   (sidebar shell, panels, tables, pills, forms, buttons, alerts).
   Fonts are vendored separately — see vendor/fonts.css.

   Palette: cool signal-blue accent on a blue-grey neutral ground (was a
   warm teal/green), semantic status colors kept independent of the
   accent. Radius: a sharp 2/3/4/6px scale (was 6/10/16px + pill) — status
   badges are square tags, not pills. Typography: --font-display and
   --font-mono are both JetBrains Mono — one unified operations-console
   monospace register for headings/nav/labels/table heads *and* raw data
   (addresses, counters) alike — while --font-ui (IBM Plex Sans) stays on
   body copy and form microcopy for readability at length.
   Both a light and a dark palette are defined. The bare :root (no
   data-theme attribute) follows the OS/browser color-scheme; the sidebar
   toggle (see layout.html) stamps documentElement with
   data-theme="light"/"dark" to override that, storing the choice in
   localStorage so it survives page navigation. */
