- Menü aus Header entfernt, neuer Eintrag unter Produkte > Scanner - Barcode-Erkennung: patchSize medium, grösserer Scan-Bereich, höhere Frequenz - Timeout-Hinweis nach 8s wenn kein Barcode erkannt wird - Tab-Wechsel (Order/Shop/Inventur) ohne Seitenreload, Kamera bleibt aktiv - PWA: gleiche Tab-Logik, Buttons statt Links - Changelog und README aktualisiert Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
