Description
Thanks for great tool!
I ran into a problem during testing. Normalized score is `-1` sometimes.
For example Overall Score and LCP here:

PageSpeed Insights works well for this URL: https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fwww.vzhurudolu.cz%2Famp (As I know this is different Lighthouse setup.)
Maybe there should be option for returning Lighthouse JSON output to have possibility to debug issues like this.

Contributor guide
Research direction
Start by reproducing the reported -1 normalized scores for Overall Score and LCP with the linked URL and attached CSV. Trace how this TypeScript Node.js CLI handles Lighthouse results, then define done as explaining the discrepancy and adding a verified fix or a clearly scoped debugging-output change.
