/*
 * Produkt-Downloads – Grundgestaltung.
 *
 * Zwei Dinge sind hier Absicht:
 *
 * 1. Alle Farben leiten sich aus der Textfarbe des Themes ab (currentColor).
 *    Damit passt die Liste in helle wie dunkle Layouts, ohne dass wir die
 *    Hintergrundfarbe kennen müssen. Eigene Werte setzt man auf .pd.
 * 2. Jede Regel steht unter .pd, und bei allem, was Themes üblicherweise selbst
 *    stylen (button, a, input, ul), steht zusätzlich der Elementtyp davor.
 *    Themes treffen Buttons gern über [type="button"] – ohne den Elementtyp
 *    gewinnt deren Regel, und die Filter-Chips sehen aus wie Theme-Buttons.
