# This component lives entirely in this folder (Downloads) so it survives a
# system wipe. Run this after rebuilding to put the pieces back in place:
#   - nosignal-keybinds-gen, nosignal-keybinds  -> ~/.local/bin/
#   - NoSignal-keybindings.md (source of truth) -> ~/.local/share/nosignal/
#   - Super+/ and Super+F1 binds -> ~/.config/caelestia/hypr-user.conf
#
# Safe to re-run (idempotent). Deps: awk, fuzzel, optional wl-copy.
