/* Leveler: game styles. Colors and fonts come from ../shared/eg-theme.css.
   Rule for this game: a tile never changes color when you hover over it or press it. It only changes when its level changes.
   (On a phone, a hover color can stay stuck after a tap and make a tile look like it is at the wrong level.)
   So there are no :hover rules anywhere in this file. */
