Rui CarmoAfter a lot of delays and issues with setting up the new build worker, I finally managed to get it running on a spiffy new ARM VM.
The main cause for the delay is that it took me a while to sort various legacy assumptions I needed to replicate in a docker-compose environment (as well as modernizing all my secrets handling), but I am now able to build and deploy the site in a slightly more modern way than before, although there are a few quirks that I still need to iron out.
I will eventually nuke the entire thing and redeploy from scratch, but for now it is working well enough to get the site back up and running.
