This pattern uses alternation (|) to match each of the target items exactly. For each target item:

1. For graph edge notations, I escape special characters like brackets and quotes.
2. For the nested parentheses string, I escape the quotes and all parentheses.
3. For equations, I escape special characters like ^ (caret), + (plus), and parentheses.
4. For IPv6 addresses, I escape the colons and slashes.
5. For email addresses with plus-tagging, I escape the plus sign.
6. For JSON-like strings, I escape quotes, colons, commas, and braces.
7. For the ROT13 string, I escape the colon.

Each item is matched exactly as is, with proper escaping for regex special characters.
