/* nuelo.app — statisches Stylesheet, keine Abhängigkeiten, kein Build.
 *
 * Eine Idee trägt die Seite: sie ist selbst eine vermaßte Zeichnung. Links läuft
 * eine Maßschiene mit, die den Abschnitt benennt, in dem man gerade steht;
 * Trennlinien ziehen sich beim Erreichen wie eine Bemaßung im Plan; das
 * Punktraster des Scanners liegt auf den Flächen. Daraus kommt auch die
 * Abwechslung: jeder Abschnitt greift ein anderes Element derselben
 * Zeichensprache auf, statt ein anderes Design zu sein.
