rega, row 46 at 835ec1ac: on the prayer map neither the shared-point sentence nor the standing pin note
appeared. research-map and countries-map provide normalizedPeopleGroups to their legends; the prayer map
did not, so its legends fell back to dataStore's cache, which holds the RAW API rows: field names the
co-location index cannot read, and no GeoJSON geometry for the standing-note detector to find.
useMapData now provides the normalized rows it draws, so every map built on it offers them. LegendMobile
and SemanticTreeLegend read them first (the cache stays the fallback), and the detector accepts a row with a
name and a position as well as a GeoJSON point. check:approx-pin-note asserts the provide and the
normalized-row match; the provide check fails on the previous useMapData.
