  /* Quit-confirm overlay — shared across all 4 game modes (Quiz/Sentences/
     Stream, Time Attack, Memory Match, Conjugate). Replaces window.confirm()
     — see game-quiz.js's showQuitConfirm/cancelQuitConfirm/
     confirmQuitCurrentMode and navigation.js's BACK_QUIT_HANDLERS handling
     for why. Deliberately mirrors .menu-overlay/.menu-dropdown's layering
     (dimmed full-screen backdrop + a floating panel) rather than introducing
     a new visual pattern, but with an actual darkened backdrop since this
     needs to read as a blocking modal, not a dismissible dropdown. */
