/* ═══════════════════════════════════════════════════════════════════════════
   RECF AURORA — the shared visual language for RECF's internal apps.

   Drop this file and recf-aurora.js into a new app, wire the four things listed
   in docs/recf-aurora-theme.md, and it will look like the rest of the estate.
   Nothing in here is specific to this app; app components live alongside it in
   their own sheet and read the tokens defined here.

   THE PALETTE is RECF's: brand navy #1B365D, violet #7C3AED as the dark-mode
   accent, teal #0FA3B1 and amber #E8A33D for notices. Somebody arriving from
   another RECF app should not feel they have left.

   THEMING is Bootstrap 5.3's data-bs-theme, set before first paint by a
   blocking script in the layout and toggled in recf-aurora.js, with DARK AS THE
   DEFAULT so the apps match for anyone who has never touched the toggle.

   WHY A SEPARATE SHEET rather than _Layout.cshtml.css: MVC's CSS isolation
   scopes a layout's stylesheet to markup written directly in that layout, so a
   .btn-primary rendered by any other view never picks it up. Everything here
   has to be global to work at all.
