   NASDAN — STEM & Robotics page
   Extends tokens.css / main.css. Section-specific styles only —
   shared components (nav, footer, buttons, cta-panel) live in
   main.css. Composition: full-bleed manifesto hero, a two-column
   about split, a four-up program grid, a reversed navy "who we
   reach" split, an amber/navy pipeline strip, and the shared
   final CTA reworked for schools & partners.
