/* SquareWords theme: Ice blue (default) */
/* Layout: one calm screen. The cube sits centre stage, controls below it; results slide in under the cube.
   Look: "Ice blue" — pale-blue page, navy ink, one cobalt accent. White squares = starting letters, cobalt = yours.
   Single committed light look, used in both host themes. */
