/*
 * The sign-in pages: login, signup, forgot and reset. Refreshed on 8 October
 * 2026 in the landing page's language.
 *
 * A split screen: a photograph with one sentence on the left, held still while
 * the form scrolls, and the existing card on the right on the page's own
 * ground. The card's markup is untouched, so every rule the batteries hold on
 * these forms holds here, and the phone layout is the old one exactly, because
 * below 900px the photograph goes and the form is the first thing on screen.
 *
 * Loaded before shell.css, so every rule on a shared class is prefixed with
 * `.au` to win on specificity.
