/* =========================================
   RESPONSIVE — 1025–1325px
   Keep side-by-side layout unchanged; scale the
   whole product block down proportionally as the
   viewport narrows (fluid zoom). 1325px = 100%
   (content starts wrapping below 1325), down to
   1025px ≈ 77%. Layout/structure never changes.
   NOTE: zoom must be a unitless number, so the
   fluid value is applied by JS (main.js) — a pure
   CSS "zoom: calc(100vw/1325)" is invalid because
   calc() yields a length, not a number.
