/*
 * Quordle layout - ported from slivce/wordle/templates/wordle/quordle.html.
 * Requires tokens.css + components.css first (site header, buttons, theme
 * tokens). Game mechanics/proportions (4 boards, shrinking "small" rows,
 * quarter-colored keys) are kept faithful to the Django original - only
 * chrome (header, buttons, modal, colors) moved onto the shared design
 * system. Tile colors (--tile-correct/present/absent) are fixed, same as
 * the daily-Wordle slice - the self-serve theme picker never touches them.
