/* CSS specificity gotcha guard: several elements use `hidden` for their
   default state but also carry a class that sets `display` (.btn-icon,
   .radar-controls, etc). Author styles beat the UA's built-in
   `[hidden] { display: none }` at equal specificity, which would silently
   make those elements visible regardless of the attribute. This rule
   makes `hidden` win unconditionally. */
