Warning::
28 font weights loaded -- likely 100+ KB of unused payload
Loading 28 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: Archivo, Google%20Sans%20Text%3A400%2C500, Google%20Sans%20Text%3A400%2C500%2C700, Google%20Sans%3A400, Google%20Sans%3A700, Google%20Symbols%3Aopsz%2Cwght%2CFILL%2CGRAD%4020..48%2C100..700%2C0..1%2C-50..200.
