That error means the HTML rendered on the server is different from what React renders on the client, so hydration fails.
It usually happens when you use things like "window", "document", "localStorage", or dynamic values like "Date.now()" or "Math.random()" during server-side rendering.
Since those values are different on the client, React can’t match the markup.
To fix it, move client-only logic into "useEffect" or make sure the server and client render the same content initially.
