/* ==========================================================================
   BEFORE / AFTER GALLERY — interactive split-comparison slider
   Markup lives in: page-templates/home.php (section "8. BEFORE/AFTER")
   Drag + project switching lives in: assets/js/main.js

   How the reveal works: both images are stacked in .before-after__frame.
   The AFTER image sits in normal flow and defines the frame height; the BEFORE
   image is absolutely positioned on top and clipped to --ba-pos with clip-path.
   A transparent range input covers the frame and is the only input mechanism —
   it gives mouse drag, touch drag, click-to-jump and keyboard arrows for free.
