This pattern uses alternation to match the two valid emails, phone numbers, and dates. Negative lookbehind and lookahead ((?<!\S) and (?!\S)) ensure that each token is matched only if it is not immediately preceded or followed by non-whitespace characters—this prevents partial or embedded matches (e.g., in "phone:(+1 (234) 567-8901)"). The email sub-pattern avoids leading dots, disallows commas, and handles subdomains. The phone and date parts match only the exact valid formats provided.
