/* Four Hundred Millimetres
   Layout concept: every photo sits inside a viewfinder frame (corner brackets, mono readout strip).
   Photo first, always dark. The games are numbered as frames (01, 02 ...) because they are a real sequence.
   Type: condensed display like the engraving on a lens barrel, a plain humanist body, mono for the readouts. */
