//! Secondary panels — rendered into the right column when a toggle mode is active.
//!
//! Phase 6 (toggles): SatDials (default) | Shifts | Blueprints | Backlog | Judges.
//! Each renders a focused, single-purpose view; pressing the toggle key again
//! returns to SatDials. SatPersonaScore events auto-return from Blueprints.
