name: release-snap

# All-hosted Snap pipeline — BOTH arches. Each track = build (the shared
# build-qt-linux.yml, which yields the self-contained AppDir) -> dump-pack ->
# publish. No compilation in snapcraft; the pack runs in seconds on a runner
# with snapd. This CI upload is the SOLE publish path: the Launchpad /
# "Build from GitHub" source recipe (root snapcraft.yaml) is DELETED — core24
# has Qt 6.4.2 and the tree needs 6.8, so a source build there cannot even
# resolve its dependencies (it OOM'd on their amd64 fleet in the Slint era
# anyway).
#
# Rewritten 2026-08-25 for the Slint -> Qt frontend switch.
