The pattern is constructed to match exactly the target strings by:
1. Using alternation (|) to separate each target pattern
2. Escaping special regex characters like $, ., [, ], {, }, (, ), +, -, ^, etc.
3. Carefully handling nested quotes and backslashes
4. Preserving exact string content while ensuring regex special characters are properly escaped
5. Handling JSON-like structures by escaping quotes and braces
6. Each part is anchored to match exactly the target strings without any extra characters

The pattern is long but precise, ensuring each target string is matched exactly as required while not matching any other content in the text.
