Tellus transformation:
  The original Ecoregions2017 shapefile was converted into a global,
  30-arc-second ecoregion-ID lookup. Each latitude row is run-length encoded
  and the resulting binary is compressed with XZ. Center-point rasterization
  is authoritative; otherwise-empty coastal and small-island cells are filled
  only when touched by a source polygon. Source feature order is preserved to
  resolve overlapping polygons deterministically.

The transformed lookup retains the source ECO_ID values and is used together
with ESA WorldCover and Köppen-Geiger climate data for Tellus biome
classification.
