/* praeforge.com — the company site.
   The Praeforge look, from the mark itself: gold and coral strands on
   near-black. The same colours as the sign-in pages (praeforge-infra's
   keycloak/theme) and the policies (praeforge-infra's hosts/public/policies),
   so a visitor moving between them never sees a seam. */
