MRS talk: the 3D World (offline, no install, no internet)

On Windows
1. Right-click mrs-talk-world3d.zip, choose "Extract all...", then "Extract".
   Do not open the pages from inside the zip: the browser cannot load the folders from there.
2. Open the extracted folder mrs-talk-world3d and double-click presenter.html.
   Chrome or Edge recommended; Firefox works too.
3. Click "Open the World". Move that window to the projector and press F for full screen.
4. Drive the talk from the presenter window or a clicker:
   Right / Space / PageDown = forward, Left / PageUp = back.
   In the World: O = overview map, N = full narration notes.
Without the presenter: double-click index.html.

Keep the folders (css, js, vendor, fonts, assets) next to the two .html files.

Practising on a phone: copy mrs-talk-practice.html (one file, no folder) to the phone and open it.
Tap the right two thirds of the screen = next, the left third = back.
