A few results from sonarwhal linter

Beginne mit den Ergebnissen von npm run sonarwhal und vergleiche sie anschließend mit .sonarwhalrc und den im Bericht aufgeführten bereitgestellten Ressourcen. Prüfe package.json auf die Sonarwhal-Konfiguration und ermittle, welche der gemeldeten Probleme mit Headern, Komprimierung, Caching, Integrität und Content-Type tatsächlich bestehen; abgeschlossen ist die Aufgabe, wenn die umsetzbaren Ergebnisse behoben oder ausdrücklich als Ausnahmen konfiguriert sind.

Some random results, some may be bogus and ignored, others may potentially be legit (or already reported via Mozilla Observatory:
