# ── 持久化说明 ──────────────────────────────────────────────────────
# 默认使用 Docker named volume（适合生产，性能好）。
# 开发调试或需要直接访问数据库文件时，可改为 bind mount：
#   volumes:
#     - ./data/db:/app/data        # SQLite 数据库文件
#     - ./backups:/app/backups     # 备份输出目录
#
# 注意：bind mount 在 macOS/Windows 上文件系统性能比 named volume 差，
# 但方便直接复制/查看数据库文件。
