- Extracted drag/resize logic from Data Explorer into reusable `ui.js` utility.
- Migrated Zoom Sketch from GridStack into a free-floating, draggable, and resizable `z-30` overlay (default size 900x455).
- Restored and optimized auto-hide timing lifecycle for Close-Up mode:
- 0-5s: Clean freeze for data inspection without hovering.
- 5-8s: Fading visual countdown warning prior to panel closure.
- Implemented state flag `zoomPanelExplicitlyClosed` guaranteeing the "X" button correctly masks rapid re-triggers.
- Bound 'g' toggle shortcut to aggressively wipe/close panels when exiting God Mode entirely.
- Added visual "Mouse pointer Out of Bounds" overlay when cursor exits main radar canvas.
