/*
  DiveOne Web Cabinet (instrument baseline)

  Goals:
  - Light, calm, "instrument panel" feel (match main site)
  - Minimal ornamentation; panels feel like "instrument clusters"
  - Status colors are indicators, not decoration

  Explicit bans (enforced by review discipline):
  - No UI libraries with their own themes
  - No "material" styles
  - No bright gradients / neon accents
