Better Auth UI

@better-auth-ui/solid provides the Solid hooks and provider configuration. Core packages provide shared options factories and query helpers.

Plugin hooks are available from @better-auth-ui/solid/plugins/*. Server helpers are available from core server entrypoints.

Use Zaidan to install copied Solid components or configure TanStack Start routes. Use this section for the Solid package APIs.
