Two bugs, one line apart, both silent.
The `url(/…)` rule only matched an UNQUOTED target, so `url("/fonts/x.woff2")` — the form every
generator emits — went through untouched. And it only ran on HTML, so a linked stylesheet got the
narrow `/_bun/` rule and nothing else.
Together that meant a site's own @font-face rules kept pointing at `/fonts/…`, which inside the frame
is the platform's root. Every face 404'd and the preview rendered in a system fallback: nothing looked
broken, it just looked like a different site than the one being previewed.
JavaScript keeps the narrow rule — an absolute path in JS may not be a URL. In CSS it always is.
