# Vector store + local embeddings for RAG, semantic memory, and tool
# selection. Used on core agent paths, so installed by default — the app
# still degrades to keyword fallback if they're ever missing.
# chromadb-client is the lightweight HTTP client (talks to a standalone
# ChromaDB service); fastembed runs local ONNX embeddings.

# Markdown rendering for research reports (src/visual_report.py).
# Imported at module-top so it's a hard core dep, not optional.
markdown
# HTML sanitizer for rendered research reports (src/visual_report.py). Report
# content is untrusted (LLM output over crawled pages) and report pages run
# under a relaxed CSP, so the rendered HTML is allowlist-sanitized.

# Calendar .ics import/export (routes/calendar_routes.py).

# Recurrence rule expansion for calendar events (routes/calendar_routes.py).
# Imported directly as dateutil.rrule — make it explicit even though caldav
# pulls it in transitively.

# CalDAV sync (src/caldav_sync.py). Handles PROPFIND discovery + REPORT
# fetch across Radicale, Nextcloud, Apple, Fastmail; we'd be reinventing
