Unable to run locally

README states:

```
npm install
[...]
npm run serve
```

However, this reports a series of deprecation warnings on macOS Sonoma, and `npm run serve` fails with:

```
  opensslErrorStack: [ 'error:03000086:digital envelope routines::initialization error' ],
  library: 'digital envelope routines',
  reason: 'unsupported',
  code: 'ERR_OSSL_EVP_UNSUPPORTED'
```
