 * Rotatory – Oberfläche nach dem tradeo Corporate Design System (docs/DESIGN.md, Stand 0.1).
 * Farben: ausschließlich tradeo Blue #122E45 und Weiß. Neutraltöne sind Abstufungen von tradeo Blue
 * über Deckkraft – eine offene Designentscheidung, bis das CDS Grautöne definiert (Abschnitt 3.3).
 * Ebenso offen: Radius (hier 6 px), funktionale Statusfarbe (hier #B42318, nur für Fehler/Konflikte),
 * Icon-Familie (hier schlichte Linien-SVGs, 1,75 px Strich). Kein Dark Mode, da im CDS nicht definiert.
