test(evals): accept a tagline heading when the product is named on the page

The rendered single-page check required "Acorn Notes" inside the H1. The
request asked for a visible heading, and a correct page put the brand in
its header with a tagline H1. The check now needs a visible heading and
the product named somewhere visible.
