# Yaria Desktop App — FreeBSD Uninstall Script
# Usage: sh <(curl -fsSL https://yaria.live/uninstall-freebsd.sh)
#
# Removes the Yaria desktop app from FreeBSD.
# No root/sudo required — everything lives under $HOME.
#
# System packages (webkit2-gtk_41, gtk3, ffmpeg, python3, aria2, mpv) are NOT
# removed: they are shared with other software and removing them could break it.
# PKG_REMOVE=1 opts in to removing them.
#
# POSIX sh — FreeBSD's /bin/sh, no bash required.
