/*
  ClinicOps public site stylesheet.
  Design language: "ledger". Calm, precise, Nordic-technical. Structure comes from hairlines,
  type and spacing, not from boxes and shadows. One accent (teal), one neutral family
  (green-tinted grey), one radius scale (--r: 6px, --r-sm: 4px). Status is always colour + word.
  Canonical token names live in design/DESIGN_TOKENS.md. Fonts are self-hosted (no third-party requests).
