/**
 * @emdash-cms/auth - Passkey-first authentication for EmDash
 *
 * Email is now handled by the plugin email pipeline (see PLUGIN-EMAIL.md).
 * Auth functions accept an optional `email` send function instead of a
 * hardcoded adapter. The route layer bridges `emdash.email.send()` from
 * the pipeline into the auth functions.
 *
 * @example
 * ```ts
 * import { auth } from '@emdash-cms/auth'
 *
 * export default defineConfig({
 *   integrations: [
 *     emdash({
 *       auth: auth({
 *         secret: import.meta.env.EMDASH_AUTH_SECRET,
 *         passkeys: { rpName: 'My Site' },
 *       }),
 *     }),
 *   ],
 * })
 * ```
