"""
Built-in extractor registration.

Importing this module registers all built-in extractors with the global registry.

Registration order matters: specialized extractors are registered first, then
markitdown (if available) overwrites the overlapping extensions so it becomes
the default backend.  If markitdown is not installed, the specialized extractors
remain active for their extensions.
