/* Azury PC - marketing site, 2026.
   Sister site to azurydigital.co.uk: same family (Archivo + IBM Plex Mono, self-hosted;
   deep navy + electric azure from the logo) but with a LIGHT "workbench" body so a local
   repair shop feels approachable to ordinary customers, not just gamers. The dark hero,
   the cutaway bench and the footer keep the brand's night-time circuit-board look.
   No third-party requests of any kind - the "no tracking" promise is literal. */
