/* Notification settings page.
   Namespaced with .ns- to avoid collisions; loaded globally via App.razor.

   Design intent: calm surfaces (hairline border + soft shadow), one card per surface area, and a
   scannable list of rows inside each card (no nested boxes). Mirrors the admin-statistics quality bar.
   Colors come from --mud-palette-* so light and dark both work. */
