   VerifyPro — UI completeness layer
   ═══════════════════════════════════════════════════════════════════════════

   Loaded after `app.css` by `layouts/partials/head.blade.php`, and a SEPARATE
   file on purpose: `app.css` is the V5 prototype's stylesheet, converted
   verbatim, and keeping it verbatim is what makes "does this match V5?" a
   readable diff. Everything that did not exist in the prototype — the public
   marketing shell, the error pages, loading skeletons, empty states, keyset
   controls, the console search box and the accessibility layer — lands here.

   EVERY colour below is a token declared in `app.css`'s :root and re-declared by
   each of the twelve `body[data-theme=…]` blocks. There is not one literal hex
   in this file, which is the only reason a page built from these classes is
   legible on Neon and on Bright without a second palette being maintained.
