/* =====================================================================
   NEEL OVERSEAS: home3.css  (third homepage, home-3.html)
   Structure after the trading-house reference; the finish is Neel's own:
   a full-width bright photo slider with a spec ticker under it, a
   lab "shade card" of drawdowns, liquid application drops, a specimen
   certificate of analysis, the CuPc molecule as line art, and a colour
   border that tracks how far down the page you are.
   Tokens, type, buttons, forms and product cards come from main.css.
   Motion rule: hover effects use the individual scale / translate /
   rotate properties, never `transform`, so they can't fight GSAP.
