Reines Restyling der bestehenden verschiebbaren HTML-Box: dunkles Panel, LIVE-COUNT-Header, farbige Fahrzeug-Icons (SVG) + farbige Zahlen, TOTAL- Zeile. Gleiche /api/counts-Daten, gleiche IDs, gleiches Drag/Polling. Keine Aenderung an der Video-Pipeline -> kein Performance-Einfluss. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
