#   2. Wheel              -> dist/testium-<v>-py3-none-any.whl   (PEP 427 name)
#   3. PyInstaller binary -> dist/testium-<v>
#   4. Flatpak bundle     -> dist/testium-<v>.flatpak

# release_note.txt is copied to dist/ up front (with a warning if it has no
# entry for the current version).
#
# All artifacts are collected (copied) under <repo>/dist/. Original outputs in
# src/dist/, package/*/dist/, doc/manual/ are left in place. Wheel and AppImage
# keep their original names (which already contain the version); manual,
# pyinstaller and flatpak are renamed to testium(-manual)-<version>(.suff).
#
# Re-uses scripts/build_env.sh and scripts/set_env.sh — the same pair invoked
# by run.sh — so the venv at test/tmp/.venv stays the single source of Python
# dependencies. `build` and `pyinstaller` are installed into that venv on
# demand if not already there. Flatpak and AppImage build in their own
# container/sandbox; their build.sh scripts have their own toolchain checks.
