eu: CORRECTION of our 2026-09-17 reading of unstated, which came from a subprocessor document that refused our client. Page states data residency is 'Available on Business+ and Enterprise plans', that free and Pro customers 'need to upgrade to the Business+ plan first', that only the Primary Owner can enable it, and that Sales must set it up. Without it, page states data is stored in the US.
