How to comment Tailwind CSS class soup?

OK, I think I get it now. Because of all the layers of syntax, this isn’t just a string of class names. Rather, it’s a list of strings, attributes, etc. So, I could do something like this:

class={
  [
    "phx-submit-loading:opacity-75",
    "w-full",         # foo
    "inline-flex",    # bar
    "justify-center", # baz
    ...
  ]
}

In practice, I don’t think I’d spread things out this much. Rather, I’d group related names, adding comments as needed.
