What the model said

Done! I've improved the HTML file with these key fixes:

1. **Fixed form error handling** - Removed the bug where 404 responses and errors were incorrectly treated as success. Now only `response.ok` (2xx) is treated as success, and errors show appropriate messages.

2. **Implemented proper fetch timeout** - Replaced the invalid `timeout` parameter with AbortController for proper 10-second timeout handling.

3. **Enhanced error messages** - Distinguishes between timeout errors ("Request timed out") and other errors ("Something went wrong").

4. **Improved UX** - Form feedback now scrolls into view after submission so users don't miss it.

5. **Cleaned up redundant markup** - Removed the `required` class from the form-info asterisk to avoid duplicate styling.

The form now properly validates, handles errors gracefully, and provides better feedback to users.
