/* learn.css: the Learn Arabic tool (/learn and /learn/words) in the Rahti design system (revamp, 2026-10-14).
 * Loads after site.css only: its class names (.card, .tile, .step, .grid, .cell) are the tool's own and must never meet the home
 * page's. The whole tool sits on one fixed night field (like the app's own screens), so the card, the tiles and the buttons are
 * steps of tone, not outlines. Class names and state classes are the ones the page scripts already toggle.
