/* public/css/cryptograms.css — public-facing Cryptograms styling.
 *
 * Layout for the letter-grid solver: a wrapping strip of ciphertext
 * cells, each cell showing the cipher letter on top and an input below
 * for the player's plaintext guess. Typing in one cell fills every
 * matching cipher letter across that cryptogram (shared-mapping hint).
 *
 * Dark-theme aware via the existing CSS vars. Print CSS hides
 * interactive controls and auto-reveals the plaintext so the page is
 * useful standalone.
