Two plans for the investor: Plan A ~180M, Plan B ~225M THB; Pheenix at OMS +20 %

User (October 2026): price the Pheenix galvanics line at OMS's reference
plus 20 %, and work on a new business plan in two versions, one at
roughly 180M THB and one at +25 %; the plans do not include contingency;
Plan A keeps every machine and uses cost levers only.

- total-investment.md: Pheenix block 324k to 445k USD (OMS 4-cell wet
  room with know-how transfer, EUR 234k to 321k, plus 20 %; was 320k to
  650k estimate); launch plant now ~161M to 285M THB with contingency,
  midpoint ~223M. New section "Two plans": Plan A = launch plant with
  solar PPA, metrology launch tier, corridor later, cassette and CD-R
  later, rented crane, Chinese boilers and compressor: subtotal ~161.7M
  + ramp-up reserve 10 to 20M = ~177M THB (127M to 226M). Plan B = second
  Duplex at launch (five presses), everything in: subtotal ~209.2M +
  reserve = ~224M THB (162M to 286M). Contingency listed as not in
  either price (~24M / ~31M at 15 %). The 180M / 216M answer marked
  superseded.
- revenue-model.md: operating pictures of both plans at 60 % specials.
  Plan A central EBITDA 1.73M USD, operating profit 1.34M, payback ~3.1
  yr on the plan price; adverse loses money. Plan B (1.0 / 1.25 / 1.5M
  records) central EBITDA 3.14M, operating profit 2.63M, payback ~2.2 yr;
  adverse just covers depreciation; needs ~1.25M records sold.
