Why this matters for the Core Web Vitals, and where to start fixing it
The CMS decides a lot about your Core Web Vitals before you write a line of your own code. It controls the HTML that ships, the scripts and styles that load by default, and how images are handled. Two sites on the same platform can score very differently depending on the theme and plugins, but the platform sets the starting point and the ceiling for how much you can tune.
Start with what the platform loads that you do not need. Strip the default scripts and styles that come with themes and plugins, defer the JavaScript that is not needed for the first paint, and make sure images go out in modern formats at the right size. On script-heavy platforms the biggest wins are usually in cutting and deferring what loads on every page.
