 * The pay gauge (includes/pieces/gauge.php): a turned-brass bezel screwed to the board-black panel,
 * a cream enamel dial set back under it, the needle and its brass hub standing off the dial (each on
 * its own depth, so they shift against the dial as you move over it) with a soft shadow cast below.
 * Beside it the board: the pay, and flaps for the monthly amount at 62, full retirement age and 70.
