render-blocking JavaScript delays LCP by 1-2 seconds on most WordPress sites.

Optimization plugins "fix" this by deferring everything — including jQuery. Then your site breaks because half your plugins depend on jQuery being loaded first.

The rule: defer third-party scripts, never defer jQuery, inline critical scripts.

Don't let a plugin guess. Know the order.
