{"content":"I'm creating an extremely challenging regex pattern matching scenario that combines multiple complex formats with subtle variations. This challenge includes:\n1. Nested data structures with escaped characters\n2. Email addresses with RFC-compliant but unusual formats\n3. Date/time formats with timezone variations\n4.
