/* ==========================================================================
   EmbassyFile — public site
   ==========================================================================

   HAND-WRITTEN, BECAUSE THIS PROJECT HAS NO ASSET PIPELINE. There is no Vite
   and no Tailwind here; the admin panel injects its own plain stylesheet from
   public/ for the same reason (see AdminPanelProvider::customStylesheetTag).
   That constraint is worth respecting rather than working around: it means the
   whole site deploys by copying files onto a shared host, which is where this
   application actually runs.

   The layout links this with a ?v= built from the file's modification time, so
   an edit reaches browsers without anybody clearing a cache.

   Structure:
     1. Tokens
     2. Reset & base
     3. Buttons
     4. Header & footer
     5. Hero
     6. Sections, cards, chips
     7. Pricing
     8. FAQ & prose
     9. Forms
    10. Responsive
