Why this matters for the Core Web Vitals, and where to start fixing it
The document lifecycle is the old way of measuring pages, and it still says useful things. DOM interactive marks the HTML fully parsed. DOM complete waits for the subresources. The load event is the official end of loading, and everything that listens for it (analytics, widgets, third-party tags) starts there.
A long gap between interactive and complete means resource weight, not markup. These milestones do not map onto user experience the way the vitals do, which is why they were replaced. But a page with a slow lifecycle does not produce fast vitals.
How does this affect the Core Web Vitals?
Passing CLS barely moves across the range: 79% at one end, 76% at the other. This signal does not separate passing sites from failing ones.
