/*
 * _base.css — gemeinsame Tokens + Reset + Standard-Komponenten
 *
 * Nutzung in einer Demo:
 *   1. Diese Datei in `demos/<slug>/_base.css` kopieren (oder per <link> einbinden).
 *   2. In `style.css` der Demo NUR die Theme-Variablen ueberschreiben (--paper, --ink, --accent, --font-display, --font-body).
 *   3. Komponenten-Klassen (.masthead, .btn, .footer, .demo-banner, .legal) sind universell — nicht pro Demo neu schreiben.
 *
 * Goal: ~40% Boilerplate aus Demo-style.css raus.
