/* ============================================================================
   MBA After 30
   ----------------------------------------------------------------------------
   Design system: ./design-system/DESIGN.md (Webflow, LIGHT CANVAS edition).
   White canvas, mist bands, obsidian ink, #146ef5 as the only interactive
   colour, Inter only, 4px buttons / 8px cards, hairline ash borders, no
   resting shadow, 1200px / 80px rhythm. One dark island: the founder.

   Self-contained. There is no scroll engine: every section is in document
   flow at its natural height and the page scrolls 1:1. Motion is limited to
   play-on-entry reveals (and the two-doors outline draw), all gated behind
   html.js so nothing is invisible by default.
