l'lI just chime​ in to confirm you that: yes, offset vectors are the right

There is no need for raster and CRS axis to have 1) the same dimensionality
(you want to describe a 2D grid in a 3D cube) and neither 2) the same axis

Indeed raster/CRS axis pairing can make sense only when the raster is
diligently aligned with the CRS space, otherwise that would makes no sense.
