Fonts are not homogenous: they need care and attention!

• Custom fonts #27 (add simple rules for fonts)
• Too many --font-size and --spacing variables? #49
• The trend for massive font-size (@media screen) #75
• Typography tokens, re-evaluating --css-variables #76
• Heading sizes are either small or massive (no in-between size) #89
• The difference between SF Pro and Roboto (minor) #95 (two fonts can have different baselines)
• x-height problems with system-ui and ui-monospace #71
