Buyer-Origin Concentration & FX Exposure

Not a validated historical backtest — a real one (correlating past peso crashes and hurricane seasons against buyer-nationality mix and price stability) needs years of price history we haven't collected yet. What this shows instead: each zone's buyer-nationality concentration (a Herfindahl index on an AI-estimated mix — the confidence level is shown, not hidden) combined with real, currently-measured FX volatility for the corresponding home currencies. A high concentration score paired with a high FX exposure score means a zone leans heavily on buyers from one currency zone that's currently volatile — a forward-looking exposure read, not a backtested resilience claim.
