/* ============================================================
   ZMG CAR TRADE — css/ct-base.css
   SELF-CONTAINED base layer.

   This file replaces the dependency on the root ZMG stylesheet
   (../css/style.css) so the Car Trade sub-site works ON ITS OWN —
   upload the car-trade/ folder alone and nothing breaks.

   It carries only what Car Trade actually uses from the ZMG
   design system: brand tokens, the font stacks, fluid type scale,
   a light reset and the shared utility classes (.wrap, .kicker,
   .section-head, .lead, .mono, .muted, .skip-link, .grain).

   Loaded BEFORE car-trade.css.
