/* S-3 Leadership Platform — design system.
   Palette aims for the "managerial / mature" feel of S-3:
   - Paper cream background (continuity with S-1 / S-2)
   - Deep forest green as primary (calm, grounded, leadership)
   - Burgundy as accent (mature, considered)
   - Slate blue for muted ink
   - Sand for surfaces / cards
   Serif display headings; clean sans for body.
