   OpsTree Capabilities — Horizontal Scroll Section

   Changes from original:
   • will-change moved off images by default (JS toggles per-active)
   • bounce animations pause when section is off-screen
   • content-visibility: auto on the outer wrap (skips paint when not visible)
   • Respects prefers-reduced-motion
