"""Docling Studio — unified FastAPI backend.

Single service providing document management (upload, CRUD), analysis

orchestration (async Docling processing), and PDF preview — all backed

Conversion engine is selected via CONVERSION_ENGINE env var:

- "local" → Docling runs in-process as a Python library (default)

- "remote" → delegates to a Docling Serve instance via HTTP
