# FastAPI dependencies, such as service injectors, will be defined here.
# For example:
# from ..core.services import LLMService # Assuming LLMService is defined
# from ..core.config import get_settings # Assuming a settings dependency
#
# async def get_llm_service() -> LLMService:
#     settings = get_settings()
#     # Logic to initialize and return an LLMService instance based on settings
#     # This is where the service factory pattern from your plan might be used.
#     # For now, this is a placeholder.

#         return BedrockService(aws_config=settings.aws_config)
