| <b>Troubleshooting</b> | |
| <br><br> | |
| The page does some heavy computations, so make sure: | |
| <ul> | |
| <li>To use a modern web browser (e.g. Chrome, Firefox)</li> | |
| <li>To use a fast desktop or laptop computer (i.e. not a mobile phone)</li> | |
| <li>Your browser supports WASM <a href="https://webassembly.org/roadmap/">Fixed-width SIMD</a></li> | |
| </ul> | |
