/**
 * Puzzle package styles (wave-3 comments) — intro cover + ladder HUD.
 * Self-contained so the minigame can ship without chess_vision.css.
 *
 * Sections:
 *   1) Intro cover (#m-puzzle-intro) — full-screen ready / countdown
 *   2) Ladder HUD (#chess-puzzle-ladder-hud) — rating + buttons
 *   3) Wrong-move flash (.is-puzzle-wrong)
 *
 * JS that toggles these:
 *   Puzzle.Intro, Puzzle.Hud, Puzzle.Board.flashWrong
