/* GXPOL — company site
   Same design language as the client portal: research-desk register, not
   dashboard SaaS. Libre Franklin display / IBM Plex Sans body / IBM Plex
   Mono for anything numeric or technical. Hairline rules, not floating cards.
   Deliberately avoids the recognisable AI-product looks (black + acid green,
   glassy gradients, purple orbs).

   NO MARKET DATA IS SURFACED ON THIS SITE. Figures shown are about the
   product (engine count, coverage), never live signal values. */

/* FIXED 2026-07: `a { color: var(--brand) }` has equal specificity to
   `.btn-primary` and appears LATER in the file, so it won.  The button
   rendered brand-teal text on a brand-teal fill — invisible in both themes.
   Anchor-qualified selectors (a.btn-primary) raise specificity above the
   bare element rule; the :is() list also covers hover/focus/visited so the
