 * File: assets/css/account.css
 * Description: Front-end styles for the Nister Account dashboard UI.
 * Notes:
 * - Mirrors the inline CSS in templates/account.php, but extracted so sites can cache it.
 * - Uses system fonts and avoids external assets.
 * - Provides accessible focus states and reduced-motion fallbacks.
