Number of vaults when buying "Publish"

I’m liking Obsidian more and more, I haven’t found anywhere how many vaults can be published, when buying “Publish”

I see on the purchase page, “$20 per month or $192 per year per site.”

I’ve seen that too, but the number of safes?
Probably one, not like sync, five.

Oh you mean how many vaults can be published to one site. Good question, and I don’t know.
