/* ============================================================
   Boot splash — shown while the Blazor WASM runtime downloads
   and initializes, before any component renders. Pure CSS so it
   paints immediately. Blazor replaces #app's contents on boot,
   so the splash self-clears with no teardown code.

   Uses design tokens from design-tokens.css (plain CSS linked
   ahead of this file, so the --color-* tokens are available
   pre-boot). Keep this file dependency-free of scoped/app CSS.
