/* Key Changer Engine — misheno.com/key-changer-engine/. The page's own stylesheet: depends on no misheno or keychanger.app file.
   Built from the accepted keychanger.app home (header on the red field, browser scene with the real popup, player card with
   markers 1 and 2, closed rows, closing red field, quiet footer); charts from the previous engine page, brought to the same measure.
   Red and light fields alternate: hero red, player light, benchmark red, performance light, closing red. */
