# ($XDG_DATA_HOME/velox, i.e. normally ~/.local/share/velox — the task database and
# any settings) on either `remove` or `purge`: per-user, root-owned deletion across
# every account on the system is exactly the kind of destructive multi-user operation
# that deserves its own careful design and testing, not a first cut bolted onto this
# local test package. Documented as a deliberate simplification in
# packaging/README.md, not a silent gap.
