# Notes
# - CLI arguments override env vars; env overrides JSON config; JSON overrides defaults.
# - For include/exclude card functionality enable ALLOW_MUST_HAVES=1 (Web) and use UI or CLI flags.
# - Path overrides must point to mounted volumes inside the container.
# - Remove a value or leave it commented to fall back to internal defaults.
