{"content":"I'm creating an extremely challenging regex puzzle that combines multiple complex pattern types that would be very difficult to match with a single regex. The challenge mixes patterns requiring different advanced regex techniques including: complex email formats with quotes and IPv6 addresses, JSON paths with nested escape sequences, URLs with special characters and IDNs, complex function definitions, multi-part phone numbers, Vue.js components with mixed quotes, CSV with escaped quotes, and more.
