/* styles.css is what the mines page adds to the shared theme
   (web/sdk/theme.css, docs/design/ui.md): the 5x5 board and its motion.
   Everything else -- the header, the bet panel, the toast, the history, the
   fairness panel, the layout at three widths -- is the theme's. Colours,
   durations and radii are the theme's tokens; nothing here is a literal of
   its own but the board's geometry. The cell classes (cell/closed/open/
   mine/hit/rest) come from grid.js; the motion classes (flip/boom/wave)
   from app.js, which sets them only for what the server's steps changed. */
