/**
 * Ensemble Newsletter — Frontend
 * ==============================
 * Nur --ensemble-* Variablen mit Fallbacks. Mit Ensemble-Theme uebernimmt der
 * Brand Tuner; ohne Ensemble greifen die Fallbacks (neutrale Palette).
 *
 * .es-field-row folgt dem Booking-Engine-Muster (booking-engine-frontend.css),
 * .ensemble-btn wird vom Ensemble-Frontend gestellt — hier nur der Fallback,
 * falls Ensemble fehlt (gleiche Werte, gleiche Variablen).
 *
 * Fallback-Regeln fuer Kanon-Klassen (.ensemble-btn, .es-field-row) stehen in
 * :where(), also mit Spezifitaet 0: Jede Regel eines Ensemble-Themes oder
 * Child-Themes (z. B. .es-layout-kinky .ensemble-btn) gewinnt automatisch —
 * egal in welcher Reihenfolge die Stylesheets laden. Eigene .esn-*-Regeln
 * behalten normale Spezifitaet.
