Test, validate and match regular expressions
Uses a positive lookahead to detect SCSS/CSS class selectors like `.myClass` or `.my-class` when followed by a structural delimiter (whitespace, `.`, `+`, `{`, `>`, `#`, or `:`). The class name is captured in group 1 while the overall match is zero-width, so the trailing character isn't consumed. Useful for extracting or highlighting class selectors in stylesheet parsing or linting tools.
