#   online  - bootstrap installed omarchy-* packages from the omacom-pkgs.org
#             repo on an existing Arch system, then ran install.sh.
#   offline - ISO build: archinstall pacstrapped the bundled mirror; install.sh
#             runs in the chroot before the user's first boot.
# Legacy OMARCHY_CHROOT_INSTALL and OMARCHY_ONLINE_INSTALL still work as
# shims during transition.
