AI Summary: Debug and fix the touch interaction issues in the Pathfinding Visualizer's grid. The current `event.preventDefault()` method in `gui.js` is ineffective in preventing default scroll behavior on touch devices, hindering drawing functionality. The solution requires identifying why `preventDefault()` fails and implementing a robust alternative to enable proper drawing on touchscreens.
