• The docstring for embed should be updated to describe both the text-only and multimodal embedding paths introduced in this change.

    def embed(self, texts: list[str]) -> list[list[float]]:

src/memos/embedders/universal_api.py:15

• Consider adding unit tests for the Azure provider branch to verify that the AzureOpenAI client is initialized and used correctly in embed.
