// =============================================================================
// TUTORIAL: visual_aids_tour — the keeper reference example for Phase 4/5.
//
// Main window holds four widgets being demonstrated:
//   - STATUS    : a text_show display (label-style)
//   - VOLUME    : a slider_float (interactive input)
//   - SAVE_BTN  : a button (trigger)
//   - NAME_INPUT: an input_text (typing target for the keyboard tour)
//
// Side "Controls" window has buttons that drive the visual aids:
//   - Highlight each demoed widget
//   - Toggle the mouse trail
//   - Pop a narrate callout pointing at VOLUME / SAVE_BTN
//   - Toggle auto-highlight-on-command (highlights every remote action)
//
