 * Seite 4006740089); die Begründungen der Abweichungen stehen dort. Die zwei,
 * die man beim Ändern kennen muss:
 *
 * - APV Blue (#46c0e9) hat auf Weiß nur 2.10:1. Nie Textfarbe auf hellem
 *   Grund, nur Flächen, Linien und Akzente. Auf Navy ist es 7.25:1 und darf
 *   Text sein.
 * - Die Schriften liegen selbst gehostet unter /assets/fonts (Fontsource,
 *   SIL OFL 1.1, Lizenzen daneben). Keine Anfrage an Google Fonts.
 *
 * Ausgeliefert unter /assets/app-<hash>.css; der Hash kommt aus dem Inhalt,
 * die Datei ist also unveränderlich und darf ewig im Cache liegen.
