   Settings page — visual tuning to match the Claude Design mock
   (Settings.dc.html). Uses native MudBlazor components; this file only
   supplies layout containers and a few component-level overrides, all
   scoped under .settings-page and bound to MudBlazor palette variables
   so light/dark themes both work.
