/* Piano Attack lab (2026-10-01): a 16-bit shooter laid under an engraved strip
   of sheet music. The page chrome follows the Falling Staff lab; the stage is
   two canvases with the engraving between them (js/attack-stage.js, styled by
   attack-stage.css). This file is the bench's own, per the rule. */
