/* === AkaraWeb design system v4.3 — brand orange (2026-07) ===
   v4 light layout kept; accent shifted from CheckDi-blue to the real group
   brand color — the orange/amber of the Akara diamond and CheckDi logo —
   paired with deep navy for text, metrics band, footer and the CheckDi pillar.
   Orange fills carry navy text (contrast); orange TEXT on white uses the
   darker --orange-deep so small type stays readable. Warm neutrals throughout. */
