/*
 * Farbsystem Generator – Stylesheet
 * -----------------------------------------------------------------------
 * WICHTIG (Konzept Punkt 7 – Typografie & CSS-Isolierung):
 * - Es wird KEINE eigene Schriftart / kein Webfont geladen. Die Typografie
 *   wird bewusst per `inherit` vom jeweiligen WordPress-Theme übernommen.
 * - Sämtliche Selektoren sind auf den eindeutigen Container ".fsg-container"
 *   beschränkt (gekapselt), damit weder das Plugin das Theme, noch das
 *   Theme unkontrolliert das Plugin beeinflusst.
 * - Es werden ausschließlich CSS Custom Properties innerhalb des Containers
 *   definiert, um Kollisionen mit globalen Variablen zu vermeiden.
