## Title

    Proposed fix: [TensorFlow >=2.16 / Keras 3] ValueError 'File format not supported: filepath=... Keras 3 only supports V3 `.keras` files and legacy H5 format files' when load_model() gets a SavedModel

## Body

    Recommended action: For inference, wrap the SavedModel with keras.layers.TFSMLayer(path, call_endpoint='serving_default'). To keep Keras 2 semantics, pip install tf-keras~=2.16 and set TF_USE_LEGACY_KERAS=1 (or import tf_keras as keras).
    
    Option: For inference, wrap the SavedModel with keras.layers.TFSMLayer(path, call_endpoint='serving_default'). To keep Keras 2 semantics, pip install tf-keras~=2.16 and [evidence: official_recommended_action]
    Applies when: keras>=3.0.0; tensorflow>=2.16 (Keras 3 default)
    Steps:
    1. Inference only: layer = keras.layers.TFSMLayer(path, call_endpoint='serving_default')
    2. Keep Keras 2: pip install 'tf-keras~=2.16'; export TF_USE_LEGACY_KERAS=1 before importing tensorflow
    3. Long term: re-save as model.save('model.keras')
    Expected: Import/call succeeds on the new version
