Generate and adapt a sea-duty daily routine with watch rotations, sleep protection, duty handovers, internet-budgeted work blocks, and role-specific tasks. Use when a user asks to build or optimize an onboard schedule by vessel type, role, timezone, watch model (e.g., 4/4, 3/3), fatigue constraints, or low-bandwidth life at sea.

生成并调整符合海上值班轮换、睡眠保护、交接班、互联网配额工作时段及岗位特定任务的日常作息安排。适用于用户根据船舶类型、岗位、时区、值班模式（如4/4、3/3）、疲劳约束或海上低带宽环境需求，构建或优化 onboard 日程时使用。
