//! Hand-curated, low-resolution Earth coastline, border, and reference
//! line data.
//!
//! All coordinates are `(longitude_deg, latitude_deg)`. Continental
//! outlines are closed polygons traced roughly clockwise. They have
//! enough detail to be recognizable at world scale and *not more* —
//! this is a schematic data set, not a cartographic one.
