Build, test, and debug regular expressions
Matches the literal word 'Start' followed by one or more non-word characters (such as ':', '-', or whitespace) and captures exactly two digits (00-99). With global and multiline flags, it finds all such occurrences across every line in a text file. Useful for extracting two-digit IDs, timestamps, or counters from structured logs or 'Start: 42' style markers.
