 * Scoped to .auth-page, and deliberately small: the form controls, the button
 * and the panel all come from components.css. What is here is the centred
 * page, the field error state, the in-flight button, and the panel that
 * explains a new account is not switched on yet.
 *
 * Every colour is an existing token. No shadow: nothing on this screen floats.
