/*-- emoji burst --*/

/* `.center` sections shrink-wrap to content height, and Reveal centers them
   vertically by measuring that (shrink-wrapped) box's scrollHeight. Any
   descendant whose *layout* box (via width/height/top/left) sticks out past
   the section inflates that scrollHeight and throws off Reveal's own
   centering math — this is true even with `position: fixed`, since what
   counts an element toward an ancestor's scrollable overflow is DOM
   containment, not which box its `top`/`left` resolve against.
   `transform`, unlike `top`/`left`, is purely a paint-time effect and never
   contributes to scrollHeight, so `.emoji-burst` keeps a zero-footprint box
   (matching the section exactly) and every emoji is pushed out to its
   actual on-slide position with a `translate()` instead. Offsets are in the
   deck's real 1280x720 stage pixels (see the revealjs `width`/`height` in
   the front matter): CSS transforms compose down the tree in the same
   coordinate space regardless of the responsive scale Reveal applies to
   `.slides`, so a px offset here lands in the same place at any window
   size. */
