Font family

Defaults to `system-ui, sans-serif`. Can be overridden with modern font stacks or any other web font like Atkinson Hyperlegible. If using a web font, watch Font Performance Strategies | Mandy Michael | performance.now() 2024 to be sure you're implementing in a performant way.

Font size

Set to the users preference or 18px, whichever is larger. 18px is chosen because of the increased thickness leading to improved contrast (WCAG ???). All headers use % of user setting, while ensuring a 2.5 ratio between the largest and smallest font sizes for readability.
