Validates Russian phone numbers with an optional +7, 7, or 8 country prefix, followed by a 3-digit area code (optionally wrapped in parentheses) and 3-2-2 digit groups separated by spaces, dashes, or underscores. Each digit segment is captured for easy extraction or normalization. Ideal for validating user input like +7 (999) 123-45-67 in web forms, CRM systems, or data pipelines.
