"""
Providers package.

After the refactor:
  - base.py         defines the Protocol + BaseProvider + ProviderResult
  - registry.py     defines ProviderRegistry (injectable, no globals)
  - detection/      detection providers
  - recognition/    recognition providers
  - scraper/        web-scraping providers
  - reverse/        reverse-image-search providers

There is NO module-level singleton.  Construct a ProviderRegistry via
the DI container in api/deps.py.
