+//! Showcase: Wearable Status Bar, Pickers & Actionable Dialogs
+//!
+//! Demonstrates:
+//! 1. **System Status Bar (`StatusBarWidget`)**: Real-time battery indicator, charging state, Bluetooth, DND, and clock.
+//! 2. **Time Picker (`TimePickerWidget`)**: 12h/24h segmented time selector with focus halo and bump animations.
+//! 3. **Numeric Range Picker (`NumberPickerWidget`)**: Incremental value roller with units.
+//! 4. **Actionable & Confirmation Dialogs (`ActionableDialogWidget`)**: Icon glyphs, multi-line prompts, and action choices.
+//!
+//! ### Controls:
+//! - **[Left / Right]**: Navigate fields within active picker / select dialog button
+//! - **[Up / Down]**: Increment / Decrement active picker value
+//! - **[Tab]**: Switch active widget focus (Time Picker -> Number Picker -> Dialog)
+//! - **[Space]**: Toggle Status Bar mode / trigger selected dialog action
+//! - **[Esc / Q]**: Exit
