   Dfly Inc — About page (about.html only)
   Builds on the shared components in style.css (dark page hero, section
   headings, .card, .card-icon, .feature-grid, .section-dark, FAQ, CTA
   banner). This file only adds the About-specific layouts: hero with
   illustration and two CTAs, the "Who we are" capability card, principle
   and process step lists on dark, capability groups, numbered values and
   the connected-growth diagram. Uses design tokens only.
