Most developers chase Lighthouse scores like a number.
That’s why their apps still feel slow.
Lighthouse doesn’t make your product fast. Decisions do.
A 300kb library in your critical path.
Client-side rendering where it’s not needed.
Animations that block the main thread.
That’s where performance actually breaks.
I recently worked on improving a web app from ~60 to 95+.
Not by adding tools.
By removing things.
Replacing heavy dependencies.
Shipping less JavaScript.
Letting the browser do its job.
Performance isn’t optimization.
It’s restraint.
