Re-base scale, pressing line, roadmap, revenue model and calculator on the launch plant

Launch plant (user, October 2026): one Duplex system and one Classic,
with cutting and galvanics in-house, everything in one capital round.

- scale.md: capacity table now launch plant 0.71-0.97M records/yr, the
  second Duplex as a growth option; launch utilities (450-540 kg/h on
  B-1/B-2, ~390 kW on 2 x 250 kW); calculator figure ~0.94M.
- pressing-line.md: launch plant section on top; five-press fleet kept as
  the layout fleet the hall and backbone are built for.
- roadmap.md: long-lead orders for the launch plant, no bridge stampers
  or outsourced cutting, commissioning order, what stays revenue-gated.
- revenue-model.md: operating picture of the launch plant: central
  revenue ~3.75M USD, EBITDA ~1.6M, operating profit ~1.1M, payback ~4
  yr on 216M THB, break-even ~0.3M records; adverse corner cannot cover
  depreciation. Five-press table kept and labelled.
- fleet-calculator.html: start fleet 1 Duplex + 1 Classic, target 850k,
  capex base 6.55M (cases 8.9 / 6.55 / 4.9M), Duplex beyond one, chiller
  500 kW, imported machinery 2.3M, ladder from the launch plant.
- total-investment.md: superseded note updated.

+Decided (user, October 2026): the plant launches with **one Newbilt Duplex
+system** (two HRP 12 presses, EX 50 main and EX 35 colour extruder) and
+**one Newbilt Classic**, bought in one capital round with the galvanics,
+stamper-prep and cutting room and commissioned in sequence
+([total investment](../finance/total-investment.md#launch-plant-october-2026)).
+That is ~0.71 to 0.97 million records a year on two shifts
+([scale](../scale.md#production-capacity)). The second Duplex system below
+is a growth option with its room, utility modules and ring-main tees
+reserved, not part of the investment. The five-press fleet stays the
+layout the hall and the utility backbone are built for.
