/* PaP — Richtung "Rechenheft".
 *
 * How to be a Hero erschafft Charaktere durch Rechnen: 400 Punkte verteilen,
 * Summe durch zehn, Bonus addieren. Das Regelwerk zeigt das ueber vier
 * aufeinanderfolgende Tabellen. Der Editor macht denselben Rechenweg sichtbar,
 * statt nur ein Ergebnis auszuwerfen.
 *
 * Getippte Werte stehen in Tinte, errechnete in Bleistift, Fehler in Rot.
 * Keine externen Schriften -- Google Fonts waeren ein DSGVO-Problem (§19).
