* This path is used for regular mobile browsing (NOT fullscreen/kiosk modes).
* Why scale the wrapper instead of mainContainer?
* - For mobile devices where content is larger than viewport, we need to scale the entire layout
* - The wrapper (#divTwc) contains both the main content AND the bottom navigation bar
* - Scaling the wrapper ensures both elements are scaled together as a unit
* - Content aligns to top-left for typical mobile web browsing behavior (no centering)
* - Content aligns to top-left for typical mobile web browsing behavior (no centering)
* - Uses explicit dimensions to prevent layout issues and eliminate gaps after scaling
