# Compiles Lightning from source, for Fedora COPR (mizerd/lightning-matrix) or any
# mock chroot. packaging-ci/scripts/build-copr-srpm.sh fills 0.10.0^20261004git21b6234 and
# 21b623428aacac2d20e5f2cf6efc3fd5c22a392e. The release pipeline keeps using lightning.spec, which repacks a
# staged tree; tests/test-copr-spec-parity.py keeps the two in step.
