Subject: [PATCH] Navigation: gemeinsamer Kopfbereich statt getrennter Bereiche
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Eine Leiste für alles: Gruppe "Speiseplan" (Wochenplan, Gerichte,
Allergene & Zusatzstoffe) und für Admins zusätzlich Gruppe
"Verwaltung" (Benutzer, Design). Aktiver Menüpunkt wird hervorgehoben,
die Konto-Seite nutzt denselben Header – kein Hin- und Herspringen
mehr zwischen Kantinen-Bereich und Verwaltung.
