Using the map
Computer: scroll to zoom, click and drag to move. Use Page Up and Page Down to change floors.
Phone or tablet: pinch to zoom and drag with one finger.
Why this version exists
This version preloads all SVG floors as SVG document layers and swaps visibility instead of reloading the map every time. That keeps your exact zoom/pan position, keeps the background map visible, and prevents the black screen between floor changes.
