/* Before/After - simple, self-contained slider styling
   My aim here is: looks decent out of the box, no theme dependencies, no plugin.

   IMPORTANT:
   - .ba-before = BEFORE image (base layer)
   - .ba-after  = AFTER image (overlay)
   - We reveal the AFTER overlay from the RIGHT so:
        Left  = Before
        Right = After
