"""Thailand regime — 0% on foreign-sourced income, with a caveat.

Thailand's 2024 remittance rule (Por 162/2566) made foreign income
*remitted* into Thailand in the year earned (or the next) taxable.
Money kept abroad is still untouched, and we assume the planner
holds investments in offshore custody (IBKR US/UK, Schwab) and
remits only the £100k spend. The 2024 rule does mean some of that
remittance could be taxable; for v1 we mirror the Malaysian
"foreign exempt" treatment and revisit when prod data lands.
