   buttons wander down the column in a diagonal instead of a line.

   with the max-width:22em cap above, and a block-level box takes that full
   22em in every row instead of hugging its player, which is the column-width
   problem that cap was added to solve. A browser without :has() keeps
   Bootstrap's centring and the players stagger as before: cosmetic, and the
   same as it was. */
