/* ============================================================================
   NiClinic Vendor Console — design system
   A token-driven admin theme. "Clinical console": a teal accent on cool,
   slightly teal-biased neutrals, with a persistent deep-teal sidebar rail.
   Light + dark via prefers-color-scheme, overridable by [data-theme].
   System font stack only (no external webfonts — the portal may run offline).
