"""
Format Handlers Module

Provides a pluggable system for parsing various document formats (PDF, DOCX, Markdown,
spreadsheets, source code) and extracting annotatable content with coordinate mappings.

Usage:
    from potato.format_handlers import format_handler_registry, FormatOutput

    # Auto-detect and extract content from a file
    output = format_handler_registry.extract("document.pdf")

    # Access extracted content
    text = output.text
    html = output.rendered_html
    coords = output.coordinate_map

    # List supported formats
    formats = format_handler_registry.get_supported_formats()
