%description
Provides functions for coarse-to-fine spatial and spatio-temporal
modeling, enabling fast prediction, regression, and uncertainty
quantification for moderate to large datasets. For methodological details,
see Murakami et al. (2026) <doi:10.1111/gean.70034> and related work on
generalized linear, downscaling, and dynamic spatio-temporal extensions.
