area_kind returns AREA_WATER for natural=water or any waterway tag,
but areas_of (osm.rs:207) requires a closed way -- and neither body of
water here is one.

  8  waterway=stream            (open ways, dropped: never close)
 10  natural=water              (a pond, mapped as a way)
  1  multipolygon  name=Blå havet  natural=water, 4 member ways

Blå havet -- literally "the blue sea" -- is a named lake on the campus, and it
is a relation, so it needs #8, the relation parser, as well as open-way
support.

AREA_WATER is the first entry in mesh::AREA_HEIGHTS, so it already has a
lift that keeps it above grass; what it does not have is anything that reads as
water. A flat slightly-blue polygon next to a green hill is not a lake.

Worth pairing with: the 3 golf=lateral_water_hazard and the 8 streams are the
same feature class.

`area_kind` returns `AREA_WATER` for `natural=water` or any `waterway` tag, but `areas_of` (`osm.rs:207`) requires a **closed** way -- and neither body of water here is one. ``` 8 waterway=stream (open ways, dropped: never close) 10 natural=water (a pond, mapped as a way) 1 multipolygon name=Blå havet natural=water, 4 member ways ``` **Blå havet** -- literally "the blue sea" -- is a named lake on the campus, and it is a relation, so it needs #8, the relation parser, as well as open-way support. `AREA_WATER` is the first entry in `mesh::AREA_HEIGHTS`, so it already has a lift that keeps it above grass; what it does not have is anything that reads as water.

Out of date. All 10 natural=water ways in the extract are closed and have baked as AREA_WATER since 9d5db89, so the ponds and golf water hazards already draw. Blå havet is not water at all: relation 5461804 is a place=square pedestrian square with forest inner rings. The only remaining gap is the 8 open waterway=stream ways, which need a linear-water feature rather than this polygon issue; file separately if wanted.
