Aspect	Blazor Server	Blazor WASM	Blazor United (.NET 8)
Render	Server (SignalR)	Browser (WASM)	ทั้งสอง (per component)
Sticky Session	ต้องใช้	ไม่ต้อง	ขึ้นกับ Component
Image Size	80-120MB	20-30MB (Nginx)	80-120MB
Resource	CPU+RAM มาก	น้อย (Static)	ปานกลาง
Scale	ซับซ้อน (Session)	ง่าย (Stateless)	ปานกลาง
Offline	ไม่ได้	ได้	บางส่วน
