Specials share 60 %+: revenue model, calculator and business plan re-based

User (October 2026): "lets say 60+% special prints" (the plant focuses on
special prints, not mono colours).

- Specials (splatter, marble, colour effects) run only on the Duplex
  systems, so at 60 % the Duplex sets the launch plant's output: ~0.58 /
  0.74 / 0.90M records a year (was 0.71 / 0.84 / 0.97 at ~20 %), the
  Classic at about two thirds load. Full 60/40 hall: ~2.3 to 3.6M (Duplex
  -limited, Classics about half loaded); five-press fleet unchanged. A
  hall balanced by output at 60 % would give Duplex ~70 to 75 % of the
  floor (estimate; noted, not applied).
- Blended price 3.76 / 4.49 / 5.27 USD (standard 3.40 / 3.80 / 4.25 plus
  the 0.60 / 1.15 / 1.70 specials premium on 60 %). Launch operating
  picture: revenue 2.28 / 3.65 / 5.41M USD, EBITDA 0.23 / 1.73 / 3.79M,
  operating profit -0.66 / 1.21 / 3.46M, payback ~3.8 yr central,
  break-even ~0.25M records; adverse needs ~1.1M records to cover
  depreciation. Specials' extra direct cost (coloured compound, purge,
  trim only into black) is not in the cost table yet: flagged as an
  upper bound until compound quotes.
- Calculator default specials share 20 -> 60 % (planning rates keep the
  launch plant balanced at 850k: revenue 4.14M, EBITDA 2.07M, payback
  3.3 yr, cash payback year ~4.8, IRR ~18 %).

  draft 0.2 rebuilt (sections 1, 4, 9, risks).
