+settings.py defines ~40 module-level *_REGEX patterns that drive WAF/error/
+charset/IP/title detection. A bad edit to any one of them is a silent failure
+(detection just stops firing). This compiles them all and pins the behavior of
+the high-traffic detection patterns with positive + negative cases.
