/* ==========================================================================
   BOTTLE BUILDERS - Motion and hover

   Polish layer. Everything here is additive: remove this file and the site
   still works, it is just flatter.

   One rule runs through it. Panels that contain a photographic plate are
   never given a transform, because transforming them promotes the panel to
   its own compositing layer and the filtered image inside stops painting.
   Those panels lift with shadow and border instead.
