Due to Android's security restrictions, JavaScript cannot load files directly from internal storage unless a local server is running. To work around this, the page is refreshed while a fork rewrites the HTML file in the background.

⚠️ The issue is that these operations are asynchronous, which may cause a read/write conflict and prevent the page from loading. If that happens, just press OK to reload the page.
