 * Eine Ebene für alles, was man anfasst: Feld, Auswahl, Knopf, Linie.
 * Baut ausschliesslich auf tokens.css auf. Nach components.css einbinden.
 *
 * Regeln
 *   1  Eine Rundung für alles: --radius (2 px). Feld, Zeile, Knopf, Zähler. Radio bleibt rund.
 *   2  Labels und Aufklapper: Söhne, Versalien, gesperrt. Zeilen und Knöpfe: Söhne Kraftig, normal geschrieben.
 *   3  Ruhig: Linie hell. Gewählt = helle Fläche und dunklere Linie.
 *   4  Ein Knopf: dunkel. Im Datenblatt und in Formularen .btn--block, volle Breite wie die Auswahlzeilen.
 *   5  Fokus nur per Tastatur sichtbar.
 *   6  Alles Bedienbare mindestens 44 px hoch (--tap-min), mobil 48 px.
 *   7  Ein Pfeil: feiner, breiter Chevron (14 × 8), überall derselbe.
