/* ============================================================
   DPC BEFORE / AFTER LAYOUT — dpc-before-after.css
   VERSION: 1.0.0
   ============================================================

   ARCHITECTURE
   ------------
   Styles for layout-before-after.php and dpc-before-after.js.
   Three interactive modes share a single fixed-size container:
     sidebyside — two images at 50% width
     drag       — stacked images with draggable divider
     toggle     — single image with crossfade swap

   RESPONSIVE
   ----------
   Mobile  ( < 768px )  — 1 pair per row
   Desktop ( >= 768px ) — 2 pairs per row

   All mode containers size to the same fixed stage height
   so layout never reflows when modes are switched.

   OVERLAY
   -------
   Centered modal, dark backdrop, fixed position.
   Overlay stage fills available space up to max dimensions.
