-The `LoginArea` component displays a "Log in" button when the user is logged out, and changes to an account switcher once the user is logged in. It handles all the login-related UI and interactions internally, including displaying login dialogs and switching between accounts. It should not be wrapped in any conditional logic.

+`LoginArea` displays a "Log in" button when the user is logged out, and changes to an account switcher once the user is logged in. It is an inline-flex element by default. To make it expand to the width of its container, you can pass a className like `flex` (to make it a block element) or `w-full`. If it is left as inline-flex, it's recommended to set a max width.
