Compute the area reachable from an origin within one or more travel-time budgets — walkability/cyclability rings. Costing "pedestrian" answers "how far can I walk in 15 minutes?", "bicycle" the cycling equivalent; "auto", "truck" and "motor_scooter" work too (e.g. delivery coverage). `contours_minutes` lists the ring boundaries in minutes (1-10 values, each up to 120); set `polygons` true for filled polygons ready to render as a map fill layer instead of contour lines. Returns a GeoJSON FeatureCollection, one feature per contour. Optional `exclude_polygons` for before/after scenarios ("close this bridge and recompute reachability"): an array of polygons, each an array of [lon, lat] pairs forming one ring — longitude FIRST — whose intersecting roads are excluded from the reachability search. Applies to the Valhalla engine; unsupported on the GraphHopper engine, where it is ignored.
