// Package mw provides transport-level HTTP middleware for Einherjar services.
//
// All middleware functions return func(http.Handler) http.Handler and are
// composed via [server.WithMiddleware] or chi's Use method.
//
// # Recommended middleware order (outermost first)
//
//	server.WithMiddleware(
//	    mw.Recover(),
//	    mw.RequestID(uuid.NewString),
//	    mw.RequestLogger(logger),
//	    mw.CORS([]string{"https://example.com"}),
//	)
//
// # Rate limiting
//
//	// In-memory (default — no extra dependencies)
//	store := mw.NewInMemoryRateLimiterStore(100, 20)
//	srv.Use(mw.IPRateLimit(store, logger))
//
//	// Distributed — swap store, middleware unchanged
//	store := valkeymw.NewRateLimiterStore(client, 100, 20)
//	srv.Use(mw.IPRateLimit(store, logger))
