# Shared crane build for the atradio CLI, imported by BOTH:
#   - cli/flake.nix   (standalone: `cd cli && nix build`),  src = ./.
#   - the root flake  (default package),                    src = ./cli
#
# Kept as a plain importable file (not a flake input) so neither flake needs a
# `path:` input — relative path inputs can't be locked inside a git repo and
# break `nix build` in CI ("unlocked input").
