 ## Notes
 - Trip stats new-country badges come from `agenda.stats.calculate_yearly_stats` via `year_stats.new_countries` (first-visit year, excluding `PREVIOUSLY_VISITED`).
+- Trip stats are calculated in `agenda/stats.py`:
+  - `travel_legs()` extracts airlines, airports, and stations from individual trip travel legs
+  - `calculate_yearly_stats()` aggregates stats per year including flight/train counts, airlines, airports, stations
+  - `calculate_overall_stats()` aggregates yearly stats into overall totals for the summary section
