* 各駅の乗降人員ランキング — one page per fiscal year (index.html = latest, `2024.html` …), linked from `ul.v2_linkTab`.
* Two station tables, both `table.v2_table`, distinguished by their `summary`:
*   駅別乗降人員順位表:   順位 | 路線 (one <img alt> per line) | 駅名 | 人員 | 前年比
*   直通連絡駅・共用駅:    線名 | 駅名 | 人員 | 前年比   (no rank — these stations are counted by the partner railway)
* The third table (総駅数) is not station data. 前年比 uses ▲ for a decrease.
