The plugin and capabilities repositories were standardised on `master`, and
five places said `origin main` — the setup script's sync and the Update-all
path. Swapping them to `master` would be the same mistake wearing a new name.
`HEAD` resolves to whatever the remote's default is, so the question stops
being asked, exactly as it now does for the marketplace icon URLs. Only the
LOCAL branch still needs a name.
Third time today that naming a branch was the bug: the icon URLs 404'd on four
repositories created as `master`, and these would have broken the moment the
rest were renamed to match.
