These need to be generalized out:

cc_location returns RGB for mapbox images and DEM, but single-band raster for ""elevation-tiles-prod"
cc_elevation returns single layer for mapbox DEM only

Modify so

cc_elevation defaults to "elevation-tiles-prod"
OR, probably better write some new functions with sensible names and include types that are RGB or raster, not either

might be better to move to terra once that's out

removed the @2x distinction for terrain, so all tiles are 256x256 by default (so identical calls give the same grid for the matrix party)
