 * The marker-map extension type. Importing this module registers
 * `markermap`. One marker per row, placed by `lon`/`lat` over a geometry
 * pack's outlines, carrying the row's `label` and its `value` in the value
 * column's own format, and filled from that column's conditional-formatting
 * rules through `grid.formatting.styleFor` — so a red / amber / green
 * availability wall is one rule set and one chart configuration, with no
 * chart-level thresholds and no colour column. `labels: false` leaves the
 * tooltip alone on a dense map; without `shapes` the markers draw on the
 * projection alone.
