/* Pre-boot loading splash for the Sorcha Wallet PWA. Rendered inside #app in
   index.html and shown until Blazor WASM finishes booting and replaces #app's
   content with the App component. Pure CSS — no MudBlazor tokens — because this
   paints before the MudBlazor stylesheet/theme are meaningful. Always dark: it
   is a brand surface and the user's theme is not known until the app boots. */
