I want to use a subdomain of my domain for netlify instead of my naked domain. That is, say I own example.com. I want to use netlify.example.com as the netlify deploy domain. Is this supported (From reference 2 below, I think it is)? In this case, how do I set branch subdomains, to look like branch.netlify.example.com (From ref 2, 3, I don’t think that’s how it works)? This would help me test a site at a subdomain safely and keep it off SEO.
