# Optional dependencies — install only if you use the corresponding feature.
# The app handles their absence gracefully (clear error message on first use).
#
# Note: chromadb-client + fastembed moved to requirements.txt — RAG, semantic
# memory, and tool selection are core paths, so they ship by default now.

# DuckDuckGo as a search provider option.
# Install if you want DDG in the search-provider dropdown.
# Alternatives: SearXNG, Brave, Tavily, Serper, Google PSE.

# PDF form-filling feature (fillable AcroForm detection, field extraction,
# value/annotation/signature stamping, page rendering for the form overlay).
# NOTE: PyMuPDF is AGPL-3.0. Installing it brings AGPL obligations for a
# network-served app — see ACKNOWLEDGMENTS.md. The MIT core (PDF *text*
# extraction via pypdf) works without it; this only unlocks form-filling.
