# Flatpak manifest for GridCraft, ready for a Flathub submission.
#
# Flatpak builds run offline, so the crate sources must be vendored first. From the repo root:
#
#   curl -fsSLO https://raw.githubusercontent.com/flatpak/flatpak-builder-tools/master/cargo/flatpak-cargo-generator.py
#   python3 flatpak-cargo-generator.py Cargo.lock -o packaging/linux/flatpak/cargo-sources.json
#   flatpak-builder --user --install --force-clean build-flatpak packaging/linux/flatpak/ai.storyteller.gridcraft.yml
#   flatpak run ai.storyteller.gridcraft
#
# For Flathub, replace the `dir` source with a `git` source pinned to a release tag and commit.
# The single-file .flatpak attached to each release comes from ai.storyteller.gridcraft.bundle.yml,
# which repackages the prebuilt release binaries. Keep runtime-version and finish-args identical.
