/* ══════════════════════════════════════════════════════════════════════════
   FLOATING COMPARE BAR — Professional cross-browser implementation
   ══════════════════════════════════════════════════════════════════════════
   ZERO transform on position:fixed — this is the definitive fix.

   transform+position:fixed is broken in Firefox/Incognito because:
   · Firefox creates a new compositor layer for transformed elements
   · Any ancestor with transform (Shoptimizer sticky header uses
     transform:translateZ(0)) makes position:fixed children lose their
     viewport-relative positioning — they stack relative to the ancestor
   · Chrome Incognito and Firefox Private Browsing use stricter compositor
     rules that expose this bug even when normal Chrome hides it

   Solution: opacity+visibility transition (zero layout/position side-effects,
   hardware-accelerated on the opacity layer, identical in all browsers).
   Body gets padding-bottom equal to bar height so content is never obscured.
