/* ==========================================================================
   Wardline — Loom design system + Wardline accent, layered on Material.

   Strategy:
   - Material owns the light/dark toggle. We do NOT add a custom toggle and we
     do NOT use light-dark()/[data-theme]; we map semantic tokens under
     Material's own scheme selectors ([data-md-color-scheme="default"|"slate"])
     and override Material's --md-primary/--md-accent variables there.
   - OKLCH primitives are a shared Loom ramp; Wardline's accent is teal.
