St. Barthélemy is French, on the euro, in the middle of the Caribbean. Currency and compliance both arrive from Europe; the customers do not. A product built for the anglophone islands is wrong here on both counts.
Not decoration. Every one of them is a field in something we have shipped.

Money in St. Barthélemy. St. Barthélemy is a French territory on the euro, which puts it inside European payment and data rules while sitting in the middle of the Caribbean. That combination is the whole engineering story here: a product built for the anglophone islands will be wrong on both currency and compliance.
We hold every amount as integer minor units with an explicit currency code, so a euro price and an EC dollar price cannot be added together by accident. Conversion happens at one explicit boundary and nowhere else.
