/* Minimalist, mobile-first styling. #0178d4 matches the accent color
   monitor.py's console panel already uses (build_panel's border_style), so
   the site reads as the same tool rather than an unrelated skin. Ink/surface
   tokens and the status palette (good/warning/critical) below come from the
   project's validated dataviz palette - status colors are fixed (same hex in
   light and dark) rather than themed, so a "good" meter always means the
