"""
Embeddings module.

Important: keep package import lightweight.

Some callers do:
  - `from embeddings import BgeEncoder`
  - `from embeddings import CLIPImageEncoder`

But the underlying implementations may import heavy optional deps (Pillow, torch, etc).
To avoid importing those at package import time (and to allow the embedding service to boot
without importing client code), we provide small lazy factories here.
