19 font weights loaded across 3 famil(y/ies)
Warning::
19 font weights loaded -- likely 100+ KB of unused payload
Loading 19 font weights typically transfers 200-400 KB just for fonts. Most pages legitimately use 2-3 weights (regular + bold, maybe medium). Audit which weights your stylesheet actually applies and trim the Google Fonts URL accordingly. Affected families: Bai Jamjuree, Overpass, Tomorrow.
