+// Command twcss compiles a Tailwind v4 stylesheet with kjol's native engine,
+// scanning explicit content globs for utility candidates. Unlike the app bundler
+// (which is wired to the frontend tree) it takes the entry, output, and content
+// globs as flags/args, so it works for markup authored in any language — used by
+// the go-wasm-web example, whose UI is written in Go.
+//
+// Usage (globs are relative to -base; pass "**" for a recursive walk):
+//
+//	twcss -entry css/app.css -out wwwroot/app.css -base . 'webui/**/*.go' 'app/**/*.go'
