@Gargron Oh I am a total moron 🤦‍♂️ It had been so long since I'd set up Wasabi I forgot that I _had_ run an nginx proxy! All working now with the addition of that single CORS directive.

I was still troubleshooting the audio player interface when I realised that it's broken in Safari (audio only, no working visualisation or controls) but works in Chrome. I'll raise an issue if there isn't one already...
