/*
 * Plotdesk Landing V6 — Seiten-Chrome: Resets, Knöpfe, Header, Footer, Fortschritt und der
 * Vorschau-Umschalter. Tokens, Raster, Typo-Skala, Kapitelkopf, Motion-Primitive und Logo-Leiste liegen
 * in core.css (gemeinsam mit V7), Kapitel-CSS je Kapitel in sections/, Hero-CSS je Option in heroes/.
 * Design-Vertrag mit allen Regeln: docs/landing-v6.md.
 *
 * Haltung: Schweizer Raster (Müller-Brockmann, Niggli) trifft Apple-Story. Zwölf Spalten, Achterrhythmus,
 * Linien statt Kästen, warmes Papier und grünliches Schwarz statt Reinweiß und Reinschwarz, Mint als
 * einzige Farbe. Bewegung kommt aus dem Scrollen, nie aus Selbstläufern (einzige Ausnahme: die Logo-Leiste).
