very simple CI/CD setup for my [tilde.club](https://tilde.club/~simponic)

instructions:

1. generate a new ssh key with no password (i.e. @ /tmp/id_ed25519)
2. add the key to .ssh/authorized_keys @ tilde.club 
3. set SSH_CONNECTION_STRING in drone.io worker secrets to "<username>@tilde.club"
4. set SSH_KEY to (echo /tmp/id_ed25519 | base64 -e --wrap=0)
5. profit (keep it simple! don't want env vars leaking for obvious reasons....)
