/* ============================================================================
   Holding Trade — Design skin A2 (live integration, preview-gated).
   Direction A: "Графит + Кармин". Tokens distilled from
   design-proposals/v2/direction-a-graphite-crimson.html and aligned to the
   canonical brand crimson (#d92038, from the Holding Trade logo puzzle and the
   Netcraze B2C storefront). Replaces the earlier pale skin A.

   • Graphite datacenter surfaces, single crimson action colour, logo-puzzle
     accents used sparingly (category dots, partner mark).
   • Large, confident Manrope display type; Inter for body.
   • Real depth: layered hero glow, hero equipment card, premium card shadows.
   • Token NAMES are kept identical to skin-a.css so the inline var(--…) used
     in the templates keeps resolving — only the values evolve, plus A2 extras.
   • Served only to preview-cookie visitors (see app/Preview.php). The public
     site is untouched.
