/* ============================================================
   Oravine — public site design system
   ------------------------------------------------------------
   One shared vocabulary of tokens + components for every public
   page, so the marketing pages, the catalogue and the article
   pages all read as the same product.

   Everything is scoped to `.oravine-site` so the admin dashboard
   (app.css) is untouched.

   Load order: oravine.css (tailwind) → site-enhance.css → this.

   One brand identity, two scripts:

     Latin  (English, Spanish)  → Elms Sans
     Arabic (Arabic, Kurdish)   → Noto Sans Arabic

   The switch keys off the `lang` attribute that App.razor
   already sets, so adding another Arabic-script locale is a
   one-line change here and nothing else.

   Elms Sans is a licensed font and is NOT bundled with this
   repo. Its @font-face declarations live in `css/brand-fonts.css`,
   which App.razor links only once the files are actually present
   in `wwwroot/font/` — so there are no 404s while it is missing.
   Until then this stack falls through to Inter, which the site
   already loads, and nothing breaks.
