/* =========================================================================
   Dr. Notes — Web Design System
   -------------------------------------------------------------------------
   Derived from the Dr. Notes for Psychiatrists app (iOS Theme.swift /
   Android Theme.kt). Token *names* mirror the apps on purpose: background,
   surface, surfaceSecondary, textPrimary, textSecondary, accent,
   accentSubtle, danger, warning, success, divider. A change here is a change
   to look up in the apps, and vice-versa.

   What the system avoids, as the apps do: saturated fills, heavy shadows,
   decorative gradients, gold. Hierarchy comes from whitespace and type.

   Loaded on every page directly after style.css. Legacy stylesheets
   reference these tokens (var(--dn-*)) instead of hard-coded colours.
