+Options:
+  --fast    Regex-only mode (skip static HTML/CSS analysis, faster but misses linked stylesheets)
+  --json    Output results as JSON
+  --help    Show this help message
+
+Detection modes:
+  HTML files     Static HTML/CSS analysis (default, catches linked CSS)
+  Non-HTML files Regex pattern matching (CSS, JSX, TSX, etc.)
+  URLs           Puppeteer full browser rendering (auto-detected)
+  --fast         Forces regex for all files
