The files end up in `host/<subdomain>` which can be served statically.
 
 QR codes are built automatically during this process. After the configuration is updated, `create_flyer.sh` calls `generate_qr.sh` to read the URLs from `config.json` and produce `qrcode-content.png` and `qrcode-tear-offs.png`.
