// The not-found branch echoes the visitor's URL path into a code span. Built by
// hand, a backtick in the path closed the span early and everything after it
// rendered as markdown on a gno.land page. md.InlineCode sizes the fence past
// any backtick run in the content, so the payload must come back wrapped in a
// DOUBLE fence, with the backtick intact inside it. Asserting on the payload
// itself rather than on any double fence in the page: an earlier version of
// this test passed on an unrelated span elsewhere in the output.
