/*
 * ghosts.css
 * Level 3 ghost counting challenge.
 *
 * Requirements:
 * - The ghost screen must be visually centered.
 * - .ghost-zone must be a clean transparent gameplay layer.
 * - .ghost-zone must have no background, no border, no box-shadow.
 * - Ghosts must stay inside the zone; overflow is hidden as a safety layer.
 * - Desktop/tablet layout must stay stacked vertically, like mobile.
 * - The numeric input must have a clear visible border.
 * - On mobile phones, the whole ghost challenge must fit without vertical scroll.
