/* Infinity.AppShell — canonical application-shell styles.
   Global (not scoped) because the shell styles MudBlazor components (the temporary drawer) and a child
   navigation component; a scoped stylesheet cannot reach either. All classes are "infinity-" prefixed to avoid
   collisions, and every color/spacing value comes from Infinity.UI design tokens (--air-*) — never hard-coded.
   Consumed via <link href="_content/Infinity.AppShell/infinity-appshell.css" rel="stylesheet" />. */
