# Flatpak bundle for GitHub Releases — Slint binary (crates/ workspace).
#
# Rewritten 2026-07-02 for the Tauri -> Slint migration (v2.0). Builds
# packaging/flatpak/com.blitzfc.qbz.yml (network manifest) with
# flatpak-builder and attaches the .flatpak bundle to the Release.
# Flathub proper is a separate repo/manifest updated at tag time via
# scripts/update-flathub.sh (offline sources).
#
# The cargo build runs on the HOST's resources even though it happens
# inside the flatpak sandbox, so this runner needs the same swap headroom
# as release-linux.yml (qbz_ui rustc peak ~30 GB).
