/* ---------- Timeline ---------- */
/*
  ズレの原因:
  - timeline::before（縦線）は left:20px で配置
  - timeline__item は grid-template-columns: 44px 120px 1fr
  - dot は 44px 列内にあり、縦線 left:20px とずれが生じていた
  → dot を 20px 中央に来るよう、dot の width を 16px として left を 20px-8px=12px 相当にする
  → timeline::before を left:19px にして dot の中心（19+8=27 ≒ 27px）と合わせる
  → 44px 列の中心は 22px なので left:14px にすると dot 中心が 14+8=22px となり列中心と一致
