/* ========================================================================
   Build With Abdallah — Central API
   Public site design system.

   Tokens mirror the main site (buildwithabdallah.com) so both properties read
   as one brand. Authored by hand rather than compiled through Tailwind/Vite:
   this app serves its public face with no node build step, which keeps deploys
   to `composer install` + `artisan migrate`.

   Inherited house rules (same as the main site):
     - no blurred floating blobs, no spinning conic borders, no "light show"
     - depth comes from layered shadows, not glow rings
     - caps tracking stays near .12em
     - motion explains the architecture; it never just decorates
