Factory console: demo fleet of one Duplex system and one Classic

Three presses for now (D1-A, D1-B on one Newbilt Duplex system, C1
Classic) instead of the plan's two Duplex systems. Order arrivals scaled
to the smaller fleet (about 3,000 to 4,600 good records a day); press
row fills the width; landing page text updated.
