- minimal/Dockerfile: install only essential geocompkg Imports (sf, terra, spData, units, dplyr, languageserver, methods) rather than full geocompkg (which brings 60+ Suggests). Also strip RSPM binary libraries and clean apt caches to reduce layer size. - README.Rmd: add section on building leaner custom images with rocker-versioned2 install scripts, with examples and suggested upstream improvements for the Rocker project. - Re-render README.md from README.Rmd. Refs: #image-size-minimal See also: rocker-org/rocker-versioned2#340
Drops RStudio Server and only installs sf, terra, spData, units, dplyr, languageserver + GDAL/PROJ/GEOS dev libs. Size: 2.29GB vs 5.85GB base.

Summary
Reduces bloat in the
minimalimage and documents how users can build their own leaner images using rocker-versioned2.Changes to

Docker daemon is unavailable on this machine so a local size comparison could not be performed. CI will confirm the new image size (target: <4GB).
Closes #123
