// LifeScheduleTimetableConfig (four HHMM boundaries per AgentTag) crossed with
// AgentDataSetsActivityConfig (what that AgentTag can actually be seen doing), built by
// _gen_npc_schedule.py.
// This is what fills the 日程 tab of the 趴卜 NPC home page:
// BubbleFriendHomePanelStore.RefreshContent -> NpcDaliyManager:GetTodayScheduleList reads
// NpcTimeTableLists[agentType], which is fed either by SyncFavorNpcTimeTableInfos(64219939) or,
// as here, straight from the login frame's PlayerClientInfoMinor.FavorNpcDailyScheduleInfos.
// GetTodayScheduleList keeps only the slices whose ActivityId is non-zero, and OnRenderActivity
// resolves the id through ActivityConfig — a wrong id merely logs
// "[C_NpcDaliyManager] 错误的ActivityId", so the table can be regenerated freely.
// A missing or malformed file leaves the catalogue empty and LoadError explains why.
