   Palette: Swiss/minimal slate. The old panel painted the page #9e3232 red,
   which is high-saturation and tiring over long sessions. Everything now sits
   on slate-950 with a single green accent reserved for "live" state, so the
   colour carries meaning instead of decoration.

   Contrast is checked against WCAG AA (4.5:1 body, 3:1 large/UI):
     fg #f1f5f9 on bg #0b1120  -> 17.2:1
     muted #94a3b8 on card     ->  6.9:1
     dim #7c8ba1 on card       ->  5.1:1
     accent #34d399 on bg      ->  9.8:1
