Press fleet: two Newbilt Duplex systems with an extruder per press, plus a Classic

The current plan (user decision, October 2026) replaces the 50/50 target
(two semi-automatic presses and two Pheenix AD12s) with an all-Newbilt
fleet of five presses: two Duplex systems in Newbilt's two-extruder
configuration (two HRP 12 presses, an extruder each, one hydraulic unit)
and one Classic fully automatic press.

- pressing-line.md: new "Current plan" section (fleet table, what it
  means, phasing from the Single 2.1 as the first half of system 1,
  re-quote questions); site requirements per Duplex system.
- scale.md: capacity table and basis (368 to 448 records/h, ~1.06 to 1.5M
  a year on two shifts, same range as before); pressing electrical row;
  steam and cooling flagged, not re-based: five presses draw ~750 to 900
  kg/h of steam and up to ~625 kW of cooling at Newbilt's per-press
  figures, against the 400 kg/h / 250 kW sized for one Duplex.
- total-investment.md: fleet change as an added-scope row (system 2
  ~230k-300k and the Classic ~290k-460k, estimates; -60k / -160k against
  the two blocks it replaces); headline unchanged until the re-base.
- roadmap items 4, 5 and 24, revenue model mature row, crane doc (the
  Classic's weight now decides 5 t or 3.2 t), vendor landscape (AD12 is
  the comparison for the Classic), README.

The business plan docx is not regenerated.

 # Pressing Line: Equipment Plan
 
-The target press fleet is a **50/50 split between fully automated and
-semi-automatic presses**: automated presses for standard production volume,
-and semi-automatic presses for splatter and other color effects, special
-editions, and small runs, where an operator working the mold directly is an
-advantage rather than a cost. The semi-automatic side is covered by the
-Newbilt evaluation below; a fully automated press line is an open
-procurement item with two candidates: the Newbilt Classic (below) and the
-Pheenix Alpha AD12 (see the [vendor landscape](../suppliers/vendor-landscape.md)).
+## Current plan: an all-Newbilt fleet of five presses (October 2026)
+
+Two **Newbilt Duplex** systems, each in Newbilt's two-extruder
+configuration (two HRP 12 presses, each fed by its own extruder, on one
+hydraulic unit with shared control), plus one **Newbilt Classic** fully
+automatic press:
+
+| | Presses | Extruders | Hydraulics |
+|---|---|---|---|
+| Duplex system 1 | 2 semi-automatic | 2 | one unit for the system |
+| Duplex system 2 | 2 semi-automatic | 2 | one unit for the system |
+| Classic | 1 fully automatic | 1, built in | its own |
+| **Fleet** | **5: 4 semi-automatic, 1 automatic** | **5** | |
+
+This replaces the earlier target of a 50/50 split between automated and
+semi-automatic presses (two of each, with the Pheenix AD12 as the
+automated candidate). What it means:
+
+- **The semi-automatic side carries most of the volume.** Splatter and
+  other colour effects, special editions and small runs are where an
+  operator working the mould is an advantage rather than a cost, and
+  Newbilt itself recommends the Duplex for splatter. With an extruder per
+  press, the two presses of a system can run different colours or
+  compounds at the same time and neither waits on a shared extruder (our
+  reading of the flyer's configurations; confirm with Newbilt). The
+  Classic takes the long standard runs.
+- **One vendor, one mould family.** Classic and Duplex share insert sets
+  (below), so the whole fleet runs one family of moulds and spares and one
+  service relationship. The single-vendor risk is the same one the Pheenix
+  path would have carried.
+- **Phasing.** The Newbilt Single 2.1 system of the 2024 quote (one press,
+  one extruder) is the launch configuration and the first half of Duplex
+  system 1: its hydraulic aggregate is already sized for the second press.
+  The second press and extruder complete system 1; system 2 and the
+  Classic complete the fleet ([scale](../scale.md) capacity table,
+  [roadmap](../roadmap.md) item 24).
+- **Capacity** at maturity stays at ~1.0 to 1.5 million records a year on
+  two shifts, the range the [revenue model](../finance/revenue-model.md)
+  uses: four semi-automatic presses at 60 to 80 records an hour (estimate)
+  and the Classic at ~128 an hour (28 s cycle, vendor figure).
+- **Utilities do not scale from the old figures.** At Newbilt's per-press
+  figures (steam 150 to 180 kg/h, cooling up to 125 kW per press), five
+  presses draw ~750 to 900 kg/h of steam and up to ~625 kW of cooling,
+  against the ~400 kg/h steam generator and ~250 kW cooling system that the
+  2024 quote's exclusions describe for one Duplex. The boiler, chiller,
+  electrical connection and [utilities CSV](../finance/utilities-investment.csv)
+  are **not yet re-sized** for this fleet; that waits for the re-quote's
+  figures ([scale](../scale.md)).
+- **Investment**: the fleet change is carried in the added-scope table of
+  [total investment](../finance/total-investment.md) until the next
+  re-base.
+- **For the re-quote** ([roadmap](../roadmap.md) item 4): the two-extruder
+  Duplex as an upgrade of the Single 2.1 and as a second complete system;
+  the Classic's price, weight, power, steam and cooling figures; and a
+  central hydraulic supply shared by both Duplex systems (an option the
+  flyer offers).
+
+The Pheenix AD12 leaves the plan; it stays in the
+[vendor landscape](../suppliers/vendor-landscape.md) as the comparison if
+the Classic re-quote disappoints, and Pheenix stays a galvanics candidate
+([galvanics and stamper prep](galvanics.md)).
