/* ============================================================================
   Design system — dark theme, canonical source of truth for every template.

   Every page should link this file and rely on it for: tokens (:root),
   .ops-header/.ops-nav/.ops-nav-item, .page-content (+ --narrow/--wide),
   .page-header, .card/.card-header/.card-body, .btn + variants, .badge +
   variants, .filter-bar, .stats-grid/.stat-item, .form-group, .devices-table.
   Pages should only define their own inline <style> for genuinely
   page-specific things (a Leaflet map, a drawer panel, a generator form
   flow) — not by re-declaring any of the above. See CLAUDE.md's Frontend
   Notes section for the do/don't list this enforces.

   --font-mono leads with IBM Plex Mono (loaded below) rather than a generic
   system-mono stack — deliberate: this app's actual content is IP addresses,
   MACs, and numeric telemetry (RSSI/frequency/capacity), and Plex Mono's
   strong 0/O and 1/l/I disambiguation plus real engineering-instrument
   character reads as a network tool built for this, not a generic
   admin-dashboard template. --font-ui pairs it with IBM Plex Sans (same type
   family, designed together) rather than the OS default — one deliberate
   voice across chrome and data instead of "data font + whatever the OS gives
   us".
