Issue #2 に最新の理解を記録し、その内容で仕様書と実装を修正しました。

document/16_マスタードキュメント_田植え計画編.md は、「行ごとに保持するのは圃場の苗箱数」「列側に反当苗箱枚数を持つ」「種もみg/箱 は全体共通値」という前提に更新しています。コード側は backend/apps/plans/models.py と backend/apps/plans/serializers.py で計画ヘッダに seedling_boxes_per_tan を追加し、backend/apps/plans/migrations/0007_ricetransplantplan_seedling_boxes_per_tan.py も作成しました。画面は frontend/src/app/rice-transplant/_components/RiceTransplantEditPage.tsx を施肥計画寄りに組み直し、列単位のデフォルト反映と四捨五入、行ごとの苗箱数入力に寄せています。frontend/src/types/index.ts も合わせて更新済みです。

確認できたのはバックエンドの構文チェックまでで、python3 -m py_compile backend/apps/plans/models.py backend/apps/plans/serializers.py backend/apps/plans/views.py は通過しています。フロントのビルド確認まではこの環境では回していません。Issue #2 にも今回の反映内容をコメント済みです。
