Reproduction Details

to reproduce just ask

Give full code in single html
 
Create a simple HTML/JavaScript app where children can practice tracing letters using touch or mouse input. The app should display the letter outlines (A to Z) for kids to trace over. Here's what the app should include:
 
SVG-based tracing area where the letter outlines are displayed.
Users should be able to trace letters using either their fingers (on touch devices) or a mouse (on desktop).
The app should detect if the user has traced over the entire letter correctly. Once the tracing is complete, it should provide visual feedback (e.g., changing color, a sound, or a congratulatory message) and automatically move on to the next letter in the alphabet.
Ensure smooth transitions between letters and include all letters from A to Z.
Add a reset button to restart the letter tracing or retry the current letter.
Include instructions or prompts to guide kids on how to trace each letter correctly.
The interface should be simple and kid-friendly, with large letters and minimal distractions. Focus on usability and fun for young children learning to write.

Found 3 places to put Stop Sequence. 2 of them did not work. The working settings I found on the top right are not permanent.

How to set Stop Sequence to <|endoftext|> for a specific mode permanently?
