/* =============================================================================
   CHAPTERS — one isolated block per page chapter, in document order:

     0. Shared chapter utilities (reveal, pin pattern)
     1. HERO        — brand showcase + dissolve headline
     2. TICKER      — capability marquee
     3. WEB         — pinned scrollytelling chapter (#web)
     4. PAYMENTS    — pinned 3D card chapter (#payments)
     5. GAMING      — PS5-style library selector (#gaming)
     6. DISCORD     — compact teaser (#discord)
     7. CONTACT     — closing CTA band (#contact)

   Each block is self-contained: safe to tweak one chapter without side
   effects. Pinned chapters degrade to stacked static sections when JS is
   absent, on small screens, or under prefers-reduced-motion (the .is-pinned
   class is only added by js/chapters.js when pinning actually activates).
