Embedded regex flags

Discusses the use of embedded regular expression modifiers (e.g., (?i)) to control behavior like case-insensitivity within the regex pattern itself. Highlights a specific Python compatibility problem where global modifiers in the middle of a regex cause errors in Python 3.11+, and suggests using the third-party `regex` module as a workaround.
