   NASDAN — Services (full directory) page
   Extends tokens.css / main.css. Hero reuses the site's
   full-bleed dot-grid + amber-glow treatment (see portfolio.css
   / techforgood.css .porto-hero / .tfg-hero); the directory
   grid reuses the bordered-numbered-item language of
   techforgood.css's .pillar-grid, extended with a link affordance
   and grouped under five category headers so it can stand in as
   the single canonical list of every NASDAN service line. Shared
   components (cta-panel, btn-nasdan, eyebrow, section-head) live
   in main.css.
