Warning::
10 font weights loaded -- likely 100+ KB of unused payload
Loading 10 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: Oxanium, Poppins.
