"""Document API package — router aggregator.

Aggregates upload_router, crud_router, and content_router under a single
APIRouter with prefix="/api/documents". This is the ONLY file in the package
that sets the prefix — sub-routers declare no prefix (D-04).

main.py import unchanged after decomposition:
  from api.documents import router as documents_router
  app.include_router(documents_router)
