widget states cached to SQLite, loaded on startup to seed DataProjection so server restart preserves last-known data for reconnecting clients. polling: first poll runs immediately, widget list cached per-task with 30s refresh, static text polled once inline instead of looping. poll failures propagate WidgetError::SourceUnavailable to clients. render engine prepends [offline] prefix in accent color, stale data preserved below.
