"""Shared FastAPI dependencies.

Use these in route signatures to inject cross-cutting concerns:
    from app.api.deps import get_redis, get_current_user, get_settings

Actual implementations live in `app/core/`. This module is a re-export
facade so route authors don't need to know which core module owns what.
