   SAI MARINE SOLUTIONS - MOTION LAYER
   Supporting styles for the GSAP / ScrollTrigger scroll experience.

   Rules of engagement:
   - Nothing here hides content on its own. Entrance states are set by GSAP at
     runtime, so the site stays fully readable if JavaScript never runs.
   - Hover micro-interactions live in CSS (not GSAP) so they never fight the
     inline transforms GSAP writes during scroll animations.
