/**
 * Title: Authentication Domain Component Stylesheet
 *
 * Purpose:
 * - Single Responsibility: Encapsulates all layout, card containers, form controls, typography,
 *   and responsive top-bar/footer for the authentication subsystem (login, forgot-password, reset-password).
 * - Relies on root CSS variables dynamically injected by the theme_styles partial.
 *
 * Why / Why this design:
 * - DRY Principle: Unifies authentication layouts under a single .auth-* component namespace rather than duplicating stylesheets per action.
 * - Performance: Avoids redundant HTTP requests and style duplication across login and password recovery flows.
 *
 * Teaching notes:
 * - Uses responsive flexbox layout with mobile viewport adaptations.
