Undo is one menu away: the new rollback flow lists the last ten Home
Manager generations (the theme/config history is already generations,
newest marked current) and activates the picked one in a terminal —
HM's supported rollback, reversible by re-picking a newer one, so no
typed-yes gate. System-level undo deliberately links out rather than
reimplementing destructive flows in rofi: the Snapshots row opens the
existing gated flow, and 'boot an older generation (how)' fires an
instruction notification pointing at docs/RECOVERY.md §3 (which now
cross-references the menu path).
V1: template-home built, generated menu bash -n clean, row rendering
and pick-parsing verified against fixture generations output. V3
exercise queued.

Slice (d) of the docs review: docs/RECOVERY.md tells the recovery
story that existed only in pieces, ordered by symptom — bad theme/HM
change (generations, apply-known-good, git-revert the flake), desktop
won't start (TTY, greetd + user journals, VM-GL and preactivate-log
pointers), broken system change (older systemd-boot generation, then
make it stick), lost files (btrfs-assistant / nomarchy-snapshots), and
the ISO + nixos-enter last resort. Commands checked against the tree;
linked from the README file tree and §5.
