Eigener Durchgang vor dem Livegang: drei Fehler, zwei Feinheiten

Umut: "schau selbst drueber, wuerdest du so online gehen?" Nein, so nicht.

Verborgener Text stand sichtbar auf der Seite: .visually-hidden gibt es in
admin.css, aber nicht in site.css. "Bewertung: 5 von 5" neben den Sternen
und "(Pflichtfeld)" hinter jedem Formularfeld waren zu lesen - seit dem
ersten Formular. axe meldet so etwas nicht, es prueft das Ansagen, nicht
das faelschliche Sichtbarsein.

Jede Spalte war ein Kasten: Rahmen, Ecken, 30px Innenabstand von
vornherein. Eine Spalte ist ein Layoutmittel; die Karte ist jetzt eine
Einstellung. Die Demoseite wirkt dadurch ruhiger.

Der Knopf im Aufruf-Band war Tinte auf Tinte, also auf dunklem Grund fast
unsichtbar - ausgerechnet beim Handlungsaufruf. Aufruf-Band und Formular
nehmen die Akzentfarbe.

Dazu: gestapelte Karten klebten aneinander (18px), und die linke Spalte im
Kontaktbereich war halb leer.

Geprueft: 393 Tests unter PHP 8.2 und 8.4, Editortest, Browserpruefung,
axe ohne Verstoss.
