# Builds Ladybird's OWN flatpak manifest (Meta/CMake/flatpak/org.ladybird.Ladybird.json,
# maintained by the LadybirdBrowser team, CI-tested on every commit via
# .github/workflows/flatpak.yml there) rather than a manifest we maintain ourselves.
# See README.md for why. That manifest isn't standalone -- it's built from inside a full
# checkout of the Ladybird repo -- so `task clone` fetches one.

      Run the installed flatpak (host flatpak sees it too, since the distrobox shares
      ~/.local/share/flatpak). Runs fully sandboxed -- see README.md for the three sandbox
      bugs patches/ fixes to make that possible. If a crashed session left a stale
      single-instance lock, this will fail with "connect: Connection refused"; run
      `task clean-runtime`.
