Press hall: five Duplex bays and four Classic positions (balanced at 60 % specials)

User (October 2026): "change the hall layout" after the finding that the
60/40 floor split leaves the Classics about half loaded at 60 %+
specials (specials run only on the Duplex systems).

- Press hall now keeps five Duplex bays (four along the visitor
  corridor, the fifth at the head of the second row) and four Classic
  positions: 550 + 200 = ~750 m2 of ~870 m2, ~73/27 by floor, 10 to 4 by
  presses; launch plant fills one of each, growth adds Duplex first.
- Full hall: ~2.9 to 4.4M records a year at 60 % specials, Classics ~80
  to 100 % loaded (60/40 gave ~2.3 to 3.6M); ~3.2 to 4.4M at ~20 %;
  fourteen presses as before: ~2.1 to 2.5 t/h steam, up to ~1.8 MW
  cooling, a utility phase of its own.
