/* ==========================================================================
   Tactical90South / TARS — design system
   Palette taken from the TARS logo: navy ink #282E69, signal blue #427BD2,
   abyss #000732, slate #6D7A89, mist #D6D7E2. Type: Barlow (self-hosted).
   Light + dark themes driven by CSS custom properties.
   Theme resolution: <html data-theme="light|dark"> (explicit user choice)
   wins; without it, the OS preference (prefers-color-scheme) applies.
   Page templates must only use these tokens — never hard-coded colors —
   so both themes work everywhere.
