/* Think & Remember, batch 5c-1: Story Order, Spot the Difference, Mini Sudoku, Maze Run, Tangram and Same Shape, Turned.
   Loaded after games.css by those six pages. Every control is a real button of at least 44px (the main ones use --tap); nothing needs
   movement to be understood: Calm mode and reduced motion only switch off the sliding of Hoot and the pop-in of the boards. */
