lexicons.py
------------
Curated, self-contained word lists used for fully local/offline linguistic
analysis (no external API, no downloaded corpora). These are intentionally
small and interpretable so that every risk-score contribution can be traced
back to a specific matched term (explainability requirement).

In a production research deployment these lists should be expanded and
validated against a labeled corpus (e.g. CLPsych, eRisk datasets) and/or
replaced with a properly trained/fine-tuned classifier.
