 ## Zähler
 
-CSS-Klasse `badge-count` in [index.css](../frontend/src/index.css): runder Zähler in der Form der Zähler der Navigationsleiste, aber **monochrom** (grau gefüllt) statt in der Akzentfarbe.
+Komponente: [CountBadge.tsx](../frontend/src/components/CountBadge.tsx), CSS-Klassen `count-badge*` in [index.css](../frontend/src/index.css). Es gibt keine anderen Zähler-Stile mehr.
 
-- Verwendet für die Anzahl offener Einträge in den Tabs der Aufgabenlisten und der Listen.
-- Die Zähler der Navigationsleiste bleiben blau (Akzent), weil sie auf neue Inhalte aufmerksam machen.
-- Kein eckiges `badge-neutral` mehr für Zähler in Tabs.
+- **Form:** runder Kreis, mindestens 16 px, ab 100 als „99+“ (der Screenreader liest die echte Zahl). Bei 0 ausgeblendet, außer mit `showZero` (z. B. Mitgliederzahl, mobiles Menü).
+- **Farbe (`variant`):**
+  - `accent`: Hier wartet etwas auf dich. Navigationsleiste (Triage, Workspace, Aufgaben).
+  - `muted` (Standard): reine Anzahl. Tabs der Aufgabenlisten und Listen, Organisationen, mobiles Menü.
+  - Beide kommen aus den Theme-Variablen (`--accent-primary`/`--text-on-accent` bzw. `--text-muted`/`--bg-panel`) und passen sich damit jedem Theme an.
+- **Position (`position`):**
+  - `corner`: Benachrichtigungs-Badge oben rechts am nächsten `relative` Elternelement, mit Ring in der Seitenfarbe. So in der Navigation und an den Tabs. Zeilen mit solchen Tabs brauchen etwas Abstand (`gap-x-3`, `pt-2`), damit der Kreis nicht in den Nachbar-Tab ragt.
+  - `inline`: im Textfluss.
+- Zahlen im mobilen Menü (`MobileActionContext`, `badge: number`) werden automatisch als `CountBadge` gezeigt; Text-Badges wie „2 aktiv“ bleiben Textmarken.
+- **Wichtig für neue Klassen:** Tailwind entfernt Klassen aus `@layer components`, die nicht wörtlich im Code stehen. Klassennamen deshalb nie zusammensetzen (`count-badge-${variant}`), sondern ausschreiben.
