/* ==========================================================================
   Capstone theme for Plane
   Injected by the nginx layer in front of plane-proxy.

   Strategy: override Plane's PRIMITIVE design tokens (--brand-*), not its
   component classes. Everything semantic (--border-color-accent-strong,
   --background-color-accent-primary, ...) already resolves through these,
   so retinting the primitives retints the entire application and keeps
   working across Plane upgrades.

   Plane scopes its palettes with [data-theme*=light] / [data-theme*=dark].
   This sheet loads after Plane's, so equal-specificity rules win on order.
