+// Package main is a tiny end-to-end smoke harness for the readitall reader.
+// It is intentionally separate from cmd/readitall (the MCP server) and lives
+// here so you can verify the browser + markdown pipeline without an MCP
+// client in the loop.
+//
+// Usage:
+//
+//	go run ./cmd/demo <url> [css-selector]
+//
+// Example:
+//
+//	go run ./cmd/demo https://raczylo.com
