What Diot-Siaci forced us to get right
A broker does not « look at a map ». They decide a concentration, a renewal, a committee. If the strip figure and the region colour disagree, the view is unusable. So we treated map and KPIs as one selection — not two screens glued together. That is the pattern we offer a retailer, a logistics team or a property owner: objects in space, indicators on top, one filter.
What this is not
It is not Power BI with a map dropped on it. It is not a GIS for cartographers. It is a business application, assembled from bricks.
