This pattern uses alternation (|) to match exactly the 15 target items. For each item, I've carefully escaped all regex metacharacters (`.`, `+`, `(`, `)`, `[`, `]`, `{`, `}`, `\`, `/`, etc.) to ensure exact matches.

Key aspects of this pattern:
- Complex email formats with quotes and punycode domains
- IPv6 addresses with zone indices
- International phone numbers with extensions
- Date-time formats including leap seconds and timezone offsets
- Object access paths with nested properties and escaped quotes
- Multiline function calls with nested structures
- Comments with special characters
- URI formats (mailto, ldap, tel)
- Regex patterns and Unicode domains

Each pattern segment is precisely crafted to match only the specific target item and nothing else. The alternation ensures we match all 15 items without any extras.
