 * Map configured `search.popular` entries to `{ route, label }` for Search.
 *
 * Curated hrefs are authored as if mounted at root, so `basePath` is applied
 * here — matching `navigation.featured` and tab paths, and agreeing with the
 * sidebar fallback these entries replace (whose routes are already based via
 * `page.route`). `withBasePath` is idempotent and skips external URLs.
 *
 * `deployment.base` is deliberately *not* applied: routes stay deploy-base-less
 * so `createLinkRow` can prefix it at click time, same as sidebar-derived pages.
 *
 * `icon` stays a name here (like `navigation.featured`): the icon set is a
 * server-only module, so `Search.astro` resolves it to inline SVG at render.
