# Runtime deps: lfx (the BUNDLE_API surface) plus IBM SDK packages used by
# the bundled components.
#
# * ``ibm-db`` powers the Db2 Vector Store.  Gated with the same platform
#   marker we previously used in ``src/lfx/pyproject.toml`` -- the upstream
#   wheel does not ship for linux/aarch64, so the dep would otherwise
#   break ``pip install`` on that arch.
# * ``ibm-watsonx-ai`` and ``langchain-ibm`` power ``WatsonxAIComponent``
#   and ``WatsonxEmbeddingsComponent``.  Both upstreams added Python 3.14
#   support (``ibm-watsonx-ai`` 1.5.13, ``langchain-ibm`` 1.1.0), so the
#   former ``python_version < '3.14'`` markers are lifted.  ``ibm-watsonx-ai``
#   raised its floor to ``>=3.11`` on the 3.14-capable build, so the universal
#   resolver forks: a 3.14 build on the 3.14 Docker image, an older
#   3.10-compatible build elsewhere.  Kept in lockstep with langflow-base.
# * ``langchain-community`` provides the helpers DB2VS leans on.
