Debugging CSP Issues

Effective debugging techniques for CSP:

// Browser console CSP debugger
(function() {
  const observer = new PerformanceObserver((list) => {
    for (const entry of list.getEntries()) {
      if (entry.entryType === 'security-policy-violation') {
        console.error('CSP Violation:', entry);
      }
    }
  });
  
  observer.observe({ entryTypes: ['security-policy-violation'] });
})();
