Plan B re-defined: the launch plant with everything in (~210M THB); front view on the cover

- Plan B now starts like Plan A with one Duplex system and one Classic,
  but takes none of the six levers: owned solar and battery (with the BOI
  solar measure), the full metrology stack, the visitor corridor, cassette
  and CD-R, the bought crane and Thai-supplied utilities (user, 17 October
  2026). ~193.8M THB before the reserve, ~209M with it (~150M to 268M),
  ~32M (~18 %) more than Plan A; the second Duplex is a growth step from
  revenue in both (~15.4M THB, estimate).
- total-investment.md "Two plans" re-based (heading and anchor now
  "B at ~210M THB", README and roadmap links updated); revenue-model.md
  operating pictures: same volume and EBITDA as Plan A, depreciation on
  Plan B's capital (operating profit 1.26M USD central, payback ~3.7 yr);
  the extra earns nothing in the modelled table, which the docs say.
- Calculator: Plan B preset = the launch plant with contingency kept out
  (EBITDA 2.07M USD, cash payback year ~4.3, IRR ~21 %); budget card marks
  180M and 180M plus 25 %; preset label "Plan B (~210M, all in)".
- Business plan draft 0.3, both versions rebuilt: every Plan B branch of
  the three content files rewritten; renders regenerated with the
  isometric view turned to the front of the site (road, car park, office,
  corridor facade) for the cover and Figures 8 to 10.

 five Duplex systems and four Classics) are funded from revenue.
