/* Pebble Crush — the board, the strip beside it, and nothing else.

   Everything that is not specific to this game — the bars, the buttons, the
   readout, the stage, the dialogs — is in css/games/arcade.css, which every
   arcade game loads. If a rule in here would also be right for Bubble Pop, it
   is in the wrong file. */

/* Three things on this page are hidden by the `hidden` attribute rather than
   by a class: the pebble picker until there is more than one set, and the two
   readout items that only mean something in a game with a move limit.

   A bare [hidden] selector is one attribute against .ar-field and
   .ar-readout__item, and those set `display` — so the class wins and the
   hidden thing stays on screen. This is the one rule that settles it, scoped
   to this page so nothing else on the site changes. */

   The board is square — eight by eight — so a wide window leaves room going
   spare at the sides. That is where the strip goes, rather than into a bigger
   board: a match-three board with more cells on it is not a better game, it is
   a smaller target for every finger playing it. On a narrow window the strip
   drops underneath. */
