/* Colour here resolves through the same role tokens as the rest of the app.
   This file is hand-authored and served directly (App.razor links it), NOT generated,
   so it is safe to edit -- but it is outside Tailwind's pipeline, which is why it uses
   var(--color-*) directly instead of utility classes. Before the Hunaru palette it
   carried eight Bootstrap literals (#0d6efd, #198754, #dc3545, #e9ecef) that belonged
   to no theme and did not swap in dark mode.
   The rgba(0,0,0,...) drop shadows are deliberately left as-is: they are neutral
   shadows, not palette colours. */
