/* ============================================================================
   Atlas — component stylesheet
   ----------------------------------------------------------------------------
   Flat, editorial award/cash flight UI. No glow, no gradients-as-decoration.
   Consumes design tokens defined elsewhere (e.g. tokens.css / :root):

     Surfaces   --bg --surface --surface-raised
     Ink        --ink --muted-1 --muted-2 --muted-3
     Lines      --border --border-soft
     Brass      --brass --brass-deep --brass-tint-bg --brass-tint-bd
     Seat pill  --seat-bg --seat-fg
     Category   --cat-<name>-line  (swatch / arc color)
                --cat-<name>-bg    (soft fill)
     Radii      --r-card --r-pill --r-input --r-tile
     Shadow     --shadow-card --shadow-float

   Type:
     Newsreader  — headlines, destinations, prices/miles (editorial serif)
     DM Mono     — eyebrows, programs, metadata (monospace)

   Layout philosophy: mobile-first. Base rules target a phone; progressive
   `min-width` media queries layer on the desktop topbar + rail + list grid.
