/*
 * Zeka Soruları — the classroom puzzle dialog (plan 107 step 2, zeka-sorulari.js). Colours come from tokens.css, so the
 * game follows the light, dark and high-contrast themes; the figures are inline SVG coloured by the --zk-* tokens below.
 * Like marbles.css: no color-mix(), filters, blur or container queries (classroom boards run older browsers on
 * integrated GPUs), and the CSS moves only transform and opacity.
 * Fit: at 1366x768 the whole question (prompt, figure, the 2x2 options, the explanation and Yeni soru) shows without
 * scrolling; below 720px the dialog itself scrolls as one column.
