A whole new data type: offerings

Products and services a business actually sells — a localised name, a price, and the industry it belongs to, for all 27 countries.

The prices are the part I'd point at. Each is a plausible amount snapped onto a sensible grid for its size: a €25 haircut, a €1,499.99 fibre install, a €209,500 construction job. Never raw machine noise, because €1,247.83 for a haircut is exactly the tell that gives fake data away in a demo.
