+description: Black and White colour grading. This regex matches a 4-digit number (optionally
+  surrounded by parentheses), followed by any amount of text, and then detects references
+  to "black and white" in various formats. It supports `blackwhite` (no spaces), `black
+  and white`, `black-white`, "`black & white`, `black/white`, as well as shorthand
+  `BW` and `B&W`, while excluding invalid variations like `b w`, `b-w`, or `b/w`
