| OPFS Recursive Viewer | |
| This page recursively lists all files stored in the browser's Origin Private File System (OPFS), | |
| using the File System Access API. If a specific file path (defined in `targetPath`) is found, | |
| its contents are read and displayed in the <pre> block. Useful for debugging or inspecting | |
| OPFS contents in a human-readable form. | |
| NOTE: `targetPath` should be replaced with a specific OPFS file path to auto-display its content. | |
