/* =========================================================
   Case study page — split layout
   Left 33vw: sticky text panel (always white), holding ALL the
   case text in order. Right 67vw: images only, in doc order.
   The sidebar uses plain position:sticky with NO internal
   overflow/scrollbar — it scrolls in the same motion as the
   page, so the two columns are always perfectly in sync.
   Image widths are expressed as a fraction of a 1600px reference
   canvas: --w:1600 renders full-bleed (100vw); smaller values sit,
   centered, inside the 67vw media column at their true proportion.
