/*
 * UpNrun — Portfo-Leo-Skin (Web-Plattform)
 * =========================================
 * Reiner Skin/Layout-Layer im Stil des Portfo-Leo-Klons (Glas-Panels, dunkle
 * geschichtete Gradients, linke Rail-Nav, aufgeraeumtes Settings-Menue).
 *
 *  - KEIN Leoparden-/Foto-Hintergrund (Phil-Wunsch): nur Gradient-Layer.
 *  - UpNrun-Cyan (#21d4fd) bleibt Primaer-Akzent, harmonisiert mit der
 *    Portfo-Leo-Palette (Cyan/Amber/Gruen/Gold).
 *  - Aendert KEINE Funktion/Route — nur Optik + Settings-Layout.
 *
 * Quelle der Vorlage: _portfo-leo-skin-ref/portfo-leo-skin.css + settings.html.
 * Tokens werden auf das bestehende UpNrun-Variablensystem (--accent/--bg/...)
 * gemappt, damit White-Label (branding.json) weiter wirkt.
