/* =========================================================================
   ImapLAB - Oberfläche im Gmail-Stil

   Gestaltungsprinzipien, an denen sich das orientiert:
     - durchgehende Kopfleiste mit grosser, gefüllter Suche
     - links Pillen-Navigation, rechts abgerundet bis an die Fensterkante
     - sehr dichte, einzeilige Nachrichtenliste (40px)
     - gelesen = leicht eingefärbt, ungelesen = weiss und fett
     - Aktionen erscheinen erst beim Überfahren der Zeile

   Mobile-first: Basis ist das Handy, ab 768px die feste Navigation,
   ab 1100px die dreispaltige Leseansicht.
