Only card and bento-cell can make a whole region a link, each through its own href. Both stretched overlays are aria-hidden="true" tabindex="-1", so keyboard and screen-reader users cannot reach them. SPEC-160 D8 extends the existing link tag to wrap blocks, and both href attributes become shorthand that renders through it.

When the content is a single rune, the anchor goes inside that rune's root; when it is several blocks or plain prose, the engine wraps them in one positioned <div> that holds the anchor.

Lumina's .rf-card:has(.rf-card__link):hover still matches, or is moved to the shared selectorpackages/runes/src/tags/card.ts and plugins/marketing/src/tags/bento.ts, and positioned by packages/skeleton/styles/runes/card.css and bento.css.postProcess. This is a new kind of engine pass, over an element that is not a rune, which is why the item is rated complex.Completed: 2026-10-26
