   Opening.

   This used to transition max-height from 0 to 3200px. Two things were wrong
   with that, and they are the same two the patch notes hit (see the note at
   the top of CSS/patch-notes.css). Anything taller than the cap was silently
   clipped, and because the transition always covers the full 3200px whatever
   is inside, a two-line block crawled open while a long one snapped — the
   apparent speed was set by how much content there was, which is exactly
   backwards.

   grid-template-rows from 0fr to 1fr animates to the content's real height, so
   every block opens at the same rate and nothing can be cut off. The inner
   wrapper needs min-height: 0 or the grid refuses to size it below its
   content and the whole thing stays open.

   The contents, arriving behind the box.

   The staggered fade-in was a JS loop that added a class to each descendant
   and then awaited a 25ms sleep — one timer per element, on the main thread,
   with nothing to stop two runs overlapping if the block was opened and closed
   quickly. --i is set once per child by js_main.js and the delay is derived
   from it here, so the sequence is the renderer's problem and re-opening
   simply restarts it.
