/* ═══════════════════════════════════════════════════════════
   TUNEX — REMAINING SECTIONS
   Testimonials · Case Studies · Process · Marketplaces

   Each one deliberately uses a DIFFERENT mechanic, because the
   page already spends a lamp beam on the hero, a marquee on the
   FAQ and a 3D ring on services. Repeating any of those would
   make the page read as one trick applied four more times:

     Testimonials  — spotlight rotator (one quote at a time)
     Case studies  — sticky scroll-stacking cards (CSS only)
     Process       — timeline that draws itself as you scroll
     Marketplaces  — connection arcs that trace between markets

   Existing section backgrounds are kept so the page's dark/light
   rhythm is unchanged.
