   Done. @seamless-auth/svelte 0.1.0 is published from #181 and Version Packages #182. The browser project landed in fells-code/seamless-cli#260, and its verify / verify check passed in CI. That check runs the React browser specs (register, email OTP, magic link, passkey register and login, OAuth, logout) against a SvelteKit 3 reference app, on both its production build and vite dev. A local released-mode run against the published packages also passed all 13 layers.

   • Session state and auth actions, exposed idiomatically: createSeamlessAuth returns a session whose properties are runes, shared through setSeamlessAuth and getSeamlessAuth
   • Login, passkey registration and OAuth callback views, plus headless use and styling guidance (package README)
   • Route guards: requireAuth and requireGuest load functions for SvelteKit 2.26 and later, and SvelteKit 3, in @seamless-auth/svelte/kit
   • Nothing Svelte-specific in @seamless-auth/client. The screens reuse the shared flows and the stylesheet in resources/styles, and they navigate through an AuthNavigator, so routers other than SvelteKit can drive them
   • Browser project in the verify harness (feat(verify): run the browser specs against a SvelteKit app seamless-cli#260)

   A security review ran before the release. Its fixes shipped with it: dropQuery is a real replace navigation, so the magic link token and OAuth code leave SvelteKit's URL state and history; the guards run again when the session changes; and a destination outside the base path falls back to signedInPath.
