You can change it, but this time the deployment is more simple and thus more tadi web... It takes about 5 seconds to publish a new version, though this is at the cost of not using markdown but instead nonstandard html. It is about as simple to write as the markdown.
It should also be quite easy to modify the deployment, though after each such modification the server needs a proper restart which can only be done by the hoster. For that, use the fediverse to inform it to do its job.
The deployment also now works via webhook instead of action because that way it doesnt require actions to be set up.
