-### Linux Flatpak
-
-Flatpak packaging files are in `packaging/flatpak/`. The Flatpak build uses the KDE 6.10 runtime with the PySide BaseApp (provides PySide6 bindings linked against the runtime's Qt6).

-- LibRaw -- required by rawpy

-The CI workflow uses `flatpak/flatpak-github-actions` with the `ghcr.io/flathub-infra/flatpak-github-actions:kde-6.10` container image to build and produce a `.flatpak` bundle attached to each release.
