# Run configs and models go to the calling user's XDG data folder. Without STRATA_INSTALL_DIR,
# Strata defaults to <components>/../install, which is root-owned under /usr/lib/strata.
# Portage owns this package; `strata install`/`strata update` are not supported here. If you need
# them, override STRATA_INSTALL_DIR=/usr/lib/strata and run with the required permissions.
