/*
 * Full-screen auth layout: sign in (member/chooser), administrator sign in,
 * registration and trial-registration pages - loaded via
 * views/layouts/auth-header.php/auth-footer.php, NOT the app shell's
 * header.php/footer.php, so there is no navbar or page container to fight
 * with. Scoped under .auth-shell regardless, so nothing here can bleed into
 * the dashboard/admin UI if a class name is ever reused.
 *
 * Composition follows the supplied Claude Design "Bowlio Club App" SignIn
 * screen exactly: the whole viewport is a two-column grid - a plain form
 * column (badge, eyebrow, heading, fields) and a full-bleed photographic
 * hero column with a bottom-anchored gradient caption - not a centered card
 * floating on a grey page background.
