 * Ad slot box (ad-slots.md D1; the unit's markup is ad-policy.md section 4).
 * Enqueued by mu-plugin/proteinindex/ads.php on the slot pages only, after
 * brand.css, whose --tpi-* tokens it reads.
 *
 * The unit prints its own box: .tpi-ad, the .tpi-ad__label line, and one
 * 1200x300 image link. Every slot sits outside a rail (front page between
 * bands, listing and archive just inside </main>), so the box takes the
 * rail's width and the image scales down to it. The .tpi-b form outranks
 * .tpi-b.is-layout-flow > *, which would zero the margins on the home page.
