Shareholding: main investor holds at least 60 %, 40 % for sale

User, 20 Oct 2026: the main investor W wants to hold at least 60 % of
the company (the BOI-promoted company), so only 40 % is for sale.

- total-investment.md "Two plans": the 60/40 rule; Ploy Printing's
  stake, founders' shares and any further co-investor come out of the
  40 %; at Plan B's ~54M THB equity floor (3:1) and one share price
  that is at least ~32M / at most ~22M THB (arithmetic only; share
  price, valuation and in-kind shares not agreed).
- README Project Status and boi.md (foreign-ownership privilege) point
  to it.
- Business plan: section 12.2 states the split (A: ~28M / ~18M, B:
  ~32M / ~22M at the equity floor, arithmetic), the co-investment bullet
  and the decisions list name the 40 %; A and B rebuilt (63 pages each,
  TOC and em-dash check clean).

+**Shareholding (user, 20 October 2026): the main investor holds at least
+60 % of the company** that holds the plant and the BOI promotion, so at
+most **40 % is for sale** to other shareholders. Ploy Printing's stake
+(cash, in kind or both), any founders' shares and any further
+co-investor all come out of that 40 %. BOI promotion permits up to 100 %
+foreign ownership of the promoted activity ([BOI](../boi.md)), so the
+split needs no particular nationality on either side. With BOI's 3:1
+debt-to-equity ceiling Plan B needs at least ~54M THB of equity; if all
+of it were paid in at one share price, the main investor's 60 % would be
+at least ~32M THB and the 40 % at most ~22M THB (arithmetic only: the
+share price, the valuation, the total equity above the floor and any
+founders' or in-kind shares are not agreed). The terms go into the
+shareholders' agreement (business plan section 12.2).
