Idiomatic ways to handle route-guarding

export const Route = createFileRoute("/dashboard")({
  beforeLoad: ({ context, location }) => {
    // Check authentication using context
    console.log("[Dashboard Route Guard] Checking authentication:", {
      path: location.pathname,
      isAuthenticated: context.auth.isAuthenticated,
      hasUser: !!context.auth.user,
      userEmail: context.auth.user?.email,
      hasJWT: !!context.auth.jwt,
      jwtPreview: context.auth.jwt
        ? `${context.auth.jwt.substring(0, 20)}...`
        : null,
      context,
    });

    if (!context.auth.isAuthenticated || !context.auth.jwt) {
      console.log(
        "[Dashboard Route Guard] Not authenticated, redirecting to signin",
      );
      // eslint-disable-next-line @typescript-eslint/only-throw-error
      throw redirect({
        to: "/signin",
        search: {
          redirect: location.href,
        },
      });
    }
