/* Generates no box of its own, so the canvas becomes the flex item of
   .center-area directly and its percentage max-* resolve against the space
   that actually exists.

   This wrapper used to be an inline-block with auto height sitting between
   the two. A percentage max-height against an auto-height parent is
   unresolvable, so the canvas could not be sized from its container and was
   pinned to `calc(100vh - 80px)` instead — a guess at the surrounding chrome
   that was 35px short of the real 115px (55 header + 33 footer + 20/20
   .center-area padding). The canvas stayed square but .center-area clips with
   overflow: hidden, so 17.5px was cut off the top *and* bottom at any window
   height where the height constraint binds — 640x640 drawn, 640x605 visible at
   1280x720. It read as a canvas that was not square, and anything placed near
   the top or bottom edge was invisible while editing but present on export.

   The wrapper holds nothing but the canvas (verified — no JS touches
   #canvasWrap), so the shadow moves to the canvas, where it also hugs the
   artwork properly instead of a box that no longer matches it.

   Do not give this a box back without re-checking the clipping: the sibling
   pattern in pixel-process works only because *its* .canvas-wrap sits in a
   column flex container and gets a definite height from `flex: 1`. Here
   .center-area is a row, so the same rules leave the height auto again. */
