This pattern is designed to match exactly the 16 target items and nothing else. I've created a regex that uses alternation (the | operator) to join patterns that match each target item precisely. For each item, I've carefully escaped all special regex metacharacters (like ., +, ?, [, (, $, etc.) so they're treated as literal characters. Special attention was given to items with already-escaped characters like the quoted strings (where \" needed to become \\") and the multiline comment (where backslashes needed proper escaping). This approach ensures we match only the target items while avoiding any distractors in the text.
