Remove and mount the Mylar sheet (ring)

The Mylar sheet is the flexible ring that seals the gap between the gantry's dome cover and front cover — remove it to get at whatever lies behind that joint, and mount it back precisely (overlap angle, orientation, and contact with the dome all matter) so the joint stays sealed against fluid ingress.
