/* ===================================================================
   Project Verifi — product showcase (projects.html).

   Extends we-verifi-brand.css + site.css — load this file third.
   Uses the shared design tokens (--graphite, --cloud, --hairline,
   --muted, --teal, --foil-gradient, --radius, --font-display,
   --font-body, --font-mono) rather than redefining them.

   Direct structural copy of join-showcase.css (Cert Verifi's .cv-showcase
   / .cvs-* block), re-namespaced .pv-showcase / .pvs-* so both can
   exist on the same site without collision. Project Verifi uses the
   teal accent throughout (it's the same accent as Ledger's own app
   shell), swapped in wherever join-showcase.css used indigo.
