- Stopp-Button: overflow:hidden auf Video-Container, z-index auf Controls, pointer-events:none auf Quagga-Canvas damit der Button klickbar bleibt - Freitext-Lieferant wird persistent in localStorage gespeichert (hbs_config) und bei Dropdown-Aenderung sofort aktualisiert - Service Worker: Network-first fuer eigene Assets (JS/CSS), Cache-first nur noch fuer CDN-Libraries - Letzte Bestell-ID (lastOrderId) ebenfalls persistent - Migration alter localStorage-Keys in neue zentrale Config Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
