/* public/css/anagrams.css — public-facing Anagrams styling.
 *
 * Tile-based solver: each anagram shows a row of "answer slots" (empty
 * boxes, one per letter) and a row of "jumble tiles" (clickable letter
 * chips in scrambled order). Click a tile → it lands in the next empty
 * slot. Click a filled slot → letter returns to the tile row.
 *
 * Dark-theme aware via CSS vars. Print CSS hides interactive bits and
 * reveals the answer list.
