uninstall.sh

#!/usr/bin/env bash
# world80 uninstaller — reverses install.sh. Removes the config symlinks it
# created and, on request, the extras (themes, Frostify, caches, packages).
#
# Safe by default: it only unlinks symlinks that point into THIS repo, never
# touches real files, and asks before anything that holds data you might want.
# It does NOT delete the repo clone itself.

# flags:  --purge   assume yes to the optional removals (themes, frostify,
#                    caches, the ~/dotfiles symlink) — but NOT packages
#         --yes     assume yes to every prompt (implies --purge; still asks
#                    nothing, but package removal stays behind its own guard)
