   COOAAFRO-RO — scroll-driven layer (Farm Minerals recipe)
   Everything that reacts to scrolling lives here (paired with
   assets/js/scroll.js). The site works and looks right without it:
   layout-changing rules are scoped under .sd-* classes that the script
   only adds once it knows it can run (GSAP loaded, no reduced-motion
   preference), so no-JS, reduced-motion and slow-connection visitors get
   the plain static page. Brand colours are COOAAFRO's own (green/amber/
   cream), mapped onto Farm Minerals' light/dark/accent/mid/deep roles.
