Fleet: each Duplex has an EX 50 main and an EX 35 colour extruder

Correction from the user: the two Duplex systems are not in the
two-extruder configuration. Each runs two HRP 12 presses from an EX 50
main extruder with an EX 35 auxiliary extruder beside it for a second
colour; the Classic stays. Fleet still five presses. Updated in
pressing-line (table, phasing, re-quote: EX 50 vs the VEX 50 of the 2024
quote, and whether one EX 50 keeps both presses at full rate), scale,
total investment (wording; estimates unchanged), roadmap item 4, README.
