   LevelLynk — site.css
   Direction B: Graphite + Safety Orange. Rugged. Industrial. Bold.

   Dark theme throughout. Orange is an ACCENT, never a background: one CTA
   colour, thin rules, and the bar-graph in the status card. Restraint is what
   reads as "rugged" — resist adding more orange.

   No external requests anywhere in this file: system font stack, no @import,
   no url() to any host. Everything self-hosted.
