A fallback for a missing file
The page asks for a file that does not exist. Today the visitor sees an empty canvas and loading… forever.
When the player fires loadError, set #st to Mascot unavailable and hide the canvas.
What Check tests
- The message appears when the file is missing
- The canvas is hidden
