## LinkHandler · type

A link handler, as optionally passed to `interceptLinks`: called for
every local-link activation that passed the built-in exclusions, with the
resolved URL, the anchor element the activation landed on, and the DOM event.

- Return `false` to leave the link to the browser (no `preventDefault`).
- Return `true` to claim the link: default handling is prevented and the
  handler is assumed to have navigated (or decided not to) itself.
- Return nothing for the default: prevent and `go(href)`.

**Type:** `(url: URL, anchor: HTMLAnchorElement, event: Event) => boolean | void`
