Dev tip: It’s worth checking the bundle size of the packages you import to the project. You can find many popular websites for that purpose (e.g., bundlephobia, pkg-size) or IDE extensions (e.g., for VSCode import cost).

Revealing "Top 7" CLS nightmares we've seen at our work:
1️⃣ Images without dimensions;
2️⃣ Ads, embeds, or iframes without reserved space;
3️⃣ Web fonts causing FOIT/FOUT;
4️⃣ Dynamic content injection (popups, accordions, etc.);
5️⃣ Third-party scripts modifying the layout;

If you need to use window in Next.js, don’t use it directly in JSX. Put it inside a useEffect - that way it only runs on the client and avoids hydration errors.

Client Components bring interactivity and dynamic behavior to modern Next.js apps. While they still participate in server-side rendering for the initial page load, they become fully interactive on the client side after hydration.
