   60% warm neutrals · 30% cornflower blue · 10% accents.
   Contrast notes (WCAG AA, computed against these exact hexes):
   - #374151 on #FAF8F5 = 9.7:1 · #6B7280 on #FAF8F5 = 4.54:1 (body/secondary text)
   - #4F5FA8 on #FFFFFF = 5.9:1 (links, outline buttons — normal-text safe)
   - #FFFFFF on #6272B8 = 4.45:1 — under 4.5, so solid-cornflower buttons render
     their label at >=18.7px bold (WCAG "large text", threshold 3:1)
   - #374151 on #E8927C = 4.34:1 — coral CTAs use charcoal text at large-bold size
   - check icons use #3D9E6F (3.3:1 on white — meets the 3:1 non-text minimum),
     never #10B981 (2.5:1, decorative only) */
