Thanks for trying out these test pages. Version B has two different font weights from the same family: Regular and Medium/Semi-bold. Version A relies on the fonts already installed on the user's computer. Dropping the semi-bold font weight would save approx 23k, but having a regular and bold font weight felt like the minimal styles needed to support the page. Dropping the header image would save 40k. (Note: the header image hasn't been optimised using something like the HTML srcset attribute which can load different picture sizes for different devices).
