/* 99 Club Studio · Online Play safe viewport fit v2.0
 * Compact the existing, proven play layout so normal play fits in one viewport
 * on common desktop/mobile sizes. Deliberately does NOT lock html/body overflow
 * and does NOT transform the board. Small screens retain ordinary page scrolling
 * as a safety fallback instead of clipping the puzzle.
