   GARAGE GALS . BEFORE / AFTER REVEAL
   ----------------------------------------------------------------------------
   The signature draggable reveal. After image sits beneath; a clip layer shows
   the Before; a lens handle drags the divide. A range input drives it for
   keyboard + screen-reader users. JS in js/before-after.js wires the pointer.
