WebPerfWG call - December 18th 1pm ET/7pm CET/10am PT

Hey folks!

Apologies for not sending this earlier, but let's chat about WebPerf today!!

Today on the agenda
<https://docs.google.com/document/d/10dz_7QM5XCNsGeI63R864lF9gFqlqQD37B4q8Q46LMM/edit?tab=t.0#heading=h.vymbq4fse4l5>
we have a procedural discussion on the `confidence` attribute that recently
landed in Navigation Timing, a proposal to expose unused preloads and maybe
a discussion on font metrics, if we have time.

Hope to see y'all there <https://meet.google.com/agz-fbji-spp?authuser=0>!

Cheers :)
Yoav
