/* =========================================
   HERO SCROLL SECTION
   =========================================
   Architecture:
   - .hero-scroll-section  : 100vh — full viewport, traps wheel events
   - .hero-sticky          : 100vh inner wrapper, clips overflow
   - .hero-inner           : absolute, constrained by header and indicators
   - .hero-title-mask      : overflow:hidden clipping window for titles
   - .hero-boxes-stage     : relative container for three boxes
   - .hero-cta-area        : arrow btn morphs to Join btn
   - .hero-indicators-bar  : pinned 32px above bottom

   State machine (JS-driven, 3 states, 400ms CSS transitions):
     State 0 → title 1, single box, arrow
     State 1 → title 2, box scaled 0.9, arrow
     State 2 → title 3, 3 boxes, Join CTA
