/* =====================================================================
   Explainer Cards (icons/images + CTAs) — Figma 6190:24450
   A bordered white card locked to the 1240 area: header (H2 Medium 32/45 +
   Large Body 18/25 lead), a 3-up row of small feature cards, then an optional
   footer (normal-body line + a single centred CTA).

   Variants (content-flag -> root modifier class):
     default              — icon cards on a soft-blue gradient + soft-blue
                            border; shared footer CTA (Type=Icons, CTA=1).
     --cta-per-card       — gray-bordered cards, each with its own CTA button;
                            no shared footer (Type=Icons, CTA=3).
     --images             — media-panel cards (gray border) instead of icons
                            (Type=Images, CTA=1).
   Desktop styles + a mobile block (<=767.98px) that stacks the 3-up row into a
   single column and reduces the heading type. Tokens only — no raw hex where a
   token exists.
