/* ==========================================================================
   Cortaly — "Exchange Terminal" design system
   Dark-only. Square by default: depth comes from structure (re-tiered
   surfaces + strong borders + a hard, un-blurred drop-lip), never from
   rounding or soft glow. Amber = LIVE/primary, Lime = EARN/up — colour is
   signal, not wallpaper. Mono uppercase is reserved for CHROME labels
   (stat labels, table heads, badges, kickers, nav-credits); body copy and
   long strings stay sans + sentence case so German localisation and
   readability survive. No clip-path on focusable elements — it would clip
   the focus ring/border (WCAG 2.4.7). Contrast held at AA on every label.
