/**
 * Bitter Customer Files – am Theme („classic.css"/SPA) ausgerichtet.
 * Nutzt die Brand-Tokens des Themes mit Literal-Fallbacks, damit die Optik
 * im wp-admin (ohne Theme-CSS) identisch bleibt.
 *
 * Hinweis zur Spezifität: Auf „Mein Konto" liegt der Manager innerhalb von
 * `.woocommerce`, dessen Link-/Button-Regeln sonst gewinnen würden. Deshalb
 * sind Links und Buttons konsequent mit `.bitter-cfiles` präfixiert.
