Press hall laid out 60/40 for Duplex systems (special pressings first)

User (October 2026): "the factory should have more space for duplex
setups than classic, we will mainly focus on special prints and not mono
colours plan it to be 60/40 duplex classic".

- Press hall (~870 m2) planned 60/40 by floor: four Duplex bays along the
  visitor corridor and six Classic positions in the second row (440 + 300
  = ~740 m2 at 110 / 50 m2), the rest open for mould carts and staging;
  the launch plant fills one of each, growth adds Duplex systems first.
  Replaces "room for ten more Classics".
- Full hall: 8 semi-automatic presses + 6 Classics, 57/43 by press count,
  ~1,250 to 1,410 records/h gross, ~3.6 to 4.7M a year on the scale.md
  basis (was 4.7 to 5.8M for 2 Duplex + 11 Classics); ~2.1 to 2.5 t/h
  steam and up to ~1.8 MW cooling, still a utility phase of its own.
  By hourly output the six automatic Classics still press more than the
  eight semi-automatic presses (estimate).
- pressing-line.md, scale.md (capacity table, utilities), site-candidates
  .md, crane-workshop-tours.md, roadmap.md, README (the FreeCAD Payap
  model still draws the earlier layout; noted, not redrawn).
- Calculator: preset "Full hall 60/40 (4 D + 6 C)", fleet ladder Duplex
  first (1+1, 2+1, 3+2, 4+3, 4+6) plus the same floor Classic-led (2+11)
  and Duplex-only (7+0) for comparison; plant view reserves 4 Duplex
  bays and 6 Classic positions.
- Business plan draft 0.2 rebuilt (capacity table row, plot fit, layout).

Checks: renderer 720 checks pass (node budget 2,700 for the Duplex-heavy
stress preset, 60 fps), calculator regression 0 fails, level selector and
page checks clean at 390 / 1024 / 1440 px dark and light; PDF 47 pages
with a filled table of contents.
