/* Platzlicht (früher Arbeitstitel Mochi) – Komponente „Beratungsgespräch buchen“ für die Landingpage.
 * Eigenständig, alle Klassen mit Präfix bt- und unter .bt bzw. .bt-overlay gekapselt (keine Kollision mit landing.css).
 * Sieht aus und bedient sich wie das Gäste-Widget (buchen/booking.css), ohne dessen globale Klassen.
 * Nutzt die Variablen aus ../shared/tokens.css, mit Ersatzwerten falls die Datei fehlt.
 * Schriftstärken 400, 600, 700 (Knöpfe) und 800 (Überschriften). Onepage-Stil (14.10.2026): Fenster 20px, Knöpfe 6px, Felder 8px,
 * Hauptknopf schwarz, Auswahl schwarz, Braun nur als Akzent (Symbole, Links).
