/*
    Shared look of the citizen authentication pages (Components/Auth/*).

    Hand-authored - NOT compiled from wwwroot/css/sass like style.css is, so edit this file directly
    (same arrangement as design-system.css).

    Global rather than a scoped .razor.css because most elements here are rendered by child components
    (InputText, ValidationMessage) that never receive the page's scope attribute.

    Every page wraps its content in .auth-page > .auth-card, so page-specific selectors are not needed;
    the descendant rules below cover the Bootstrap classes the pages still use inside the card.
