the font is a little off - I didn't want to pay the $720 license so used a dodgy one from online, which i believe is affecting width slightly (antialiasing on and text-spacing altered, still too wide)
the font weight of the "description" box and the placeholder / value on the selects is different on the base and the AI version in figma - I used the lighter one as it's then consistent with the AI recommendations, but can of course change it if that was a mistake
