   Notes for Astro handoff:
   - All tokens declared as CSS variables on :root → trivial to port
     1:1 to src/styles/global.css.
   - Layout primitives (.nav, .footer, .container, .grid-*) are page-agnostic.
   - Page-scoped sections use BEM-ish names (.hero, .gates, .chart-card,
     etc) — each should become its own Astro component.
