/*
 * IL SITO DI TRAILGUN — chiaro, istituzionale, tipografia fine (Red Hat Display leggero sui titoli,
 * Red Hat Text sul corpo). Il gradiente del marchio (blu, viola, verde acqua: i colori del logo) sta
 * solo dove guida l'occhio: «In a flash.», l'azione principale, la pista, la velatura delle foto e i
 * pannelli scuri. I titoli di sezione restano a tinta unita. Raggi: pillola per i comandi, 20px per i pannelli.
 * Un solo momento animato per sezione che lo merita: il marchio che si compone, la pista che si
 * traccia. Con `prefers-reduced-motion` tutto è già al suo posto.
