2025-26 state analysis: code, sources and results

current_analysis/   PEN 2025-26 state map counts, Census July 2025 population,
                    FEC 2024 presidential results; run_current_analysis.py fits the
                    Poisson and negative binomial models and the leave-one-state-out
                    validation; results/ holds the saved outputs used on the website.
map/                bb_map_current.py draws the labelled 2025-26 map:
                    python bb_map_current.py map_data/us_states_2024.geojson \
                        map_data/state_analysis_2025_2026.csv map_2025_26.png

Counts are PEN-recorded instances (one title restricted in one district).
Grey or zero-coded states have no count on PEN's map; that does not establish
that no bans occurred. Rates use all residents, not students.
