 * @description Gemeinsames Stylesheet der Admin-GUI – übernommen aus dem klickbaren Prototyp
 *              (design/prototype/assets/fxarchive.css), damit die echte Oberfläche genauso aussieht.
 *              Änderungen am Aussehen bitte in BEIDEN Dateien machen oder den Prototyp künftig hieraus
 *              ableiten. Ergänzungen nur für die echte Anwendung stehen in mgmt.css.
 *              Ursprünglich für: Admin-GUI, Kundenportal, Tagesbericht, Bestätigungsseite, Outlook-Add-in. Es setzt die Gestaltungsregeln aus CLAUDE.md um:
 *              schmale dunkle Icon-Leiste, helle Inhaltsfläche, Diagramme statt Zahlenkolonnen,
 *              IBM Plex Sans/Mono, Akzentfarbe „Fuchs-Orange“ und feste Statusfarben.
 *
 *              AUFBAU:
 *                1. Farb- und Maß-Variablen (Design-Tokens) – nur hier Farben ändern
 *                2. Grundlayout (App-Rahmen mit Seitenleiste, Kopfzeile, Inhalt)
 *                3. Bausteine (Karten, Tabellen, Knöpfe, Formulare, Reiter, Schalter, Pillen …)
 *                4. Sonderseiten (Anmeldung, Tagesbericht, Add-in)
 *                5. Handy-Ansicht (das Kundenportal muss am Handy bedienbar sein)
 *
 *              Barrierefreiheit: Kontrast der Texte mindestens 4.5:1, sichtbarer Fokusrahmen für die
 *              Tastaturbedienung, echte Buttons statt klickbarer DIVs.

 * 3c. Kompakte Mail-Listen für tausende Einträge
 * Gedanken dahinter:
 *   - Eine Zeile pro Mail (32 px), alles Wichtige in einer Zeile: Kategorie-Farbbalken, Zeit,
 *     Absender, Betreff, Score. Lange Texte werden mit „…“ gekürzt, der volle Text steht im Tooltip.
 *   - Ungelesene Mails fett, gelesene normal – wie in Outlook.
 *   - Aktionen erscheinen erst beim Darüberfahren (spart eine ganze Spalte).
 *   - Lesebereich rechts (wie Outlook): Klick auf eine Zeile zeigt Vorschau, Header und „Warum?“,
 *     ohne die Liste zu verlassen. Pfeiltasten bzw. j/k blättern durch die Liste.
 *   - Die Liste scrollt in sich, Spaltenköpfe und Tagesgruppen bleiben oben stehen.
 *   - Seitenweise Anzeige (50/100/250) – der Server liefert nie tausende Zeilen auf einmal.
 *   - Umschalter „Kompakt / Komfort“ für alle, denen 32 px zu eng sind.
