I'm using the alternation operator (|) to create a pattern that matches any of the target items exactly. Each item is carefully escaped to match literally with special regex characters (., +, *, ?, etc.) preceded by backslashes. For the HTML and regex items, I've carefully escaped the quotes and other special characters. For items containing regex syntax themselves (like the "regex:" item), I've double-escaped the necessary characters to ensure they match literally. This approach ensures we match exactly the 12 target items without matching any of the distractor items that have slight differences.
