- Documents all triggers, since this repository is a starting point for people to learn from.
- Only deploys the branch named "live", which gives people more deliberate control of what gets deployed. Why not name it "main"? Because that complicates things a lot when forking this template to your own repos, since the template's default branch is also (currently) named "main", which would among other things complicate the act of syncing the fork via GitHub's web UI. The name "main" also confuses the user since it doesn't give them any hint that it's the only live-published branch.
- Only automatically builds the branches "live", "template" or "main" when pushing new commits. But builds any branch name when it's a pull request, to allow automated PR "build checks" to succeed.
