Better typographic flexibility and resilience, with or without webfonts

[thisisdano]

This epic addresses the need to build sites that perform and display well regardless of whether webfonts are used or loaded.

Issues relevant to this epic

• Address and correct for metric variations between supported typefaces (how does this affect both font size and line height?)
• Research the suitability of webfonts for government applications
• Develop a practical, performant font stack for progressive enhancement
• Scope typeface-specific styles to a trigger that the font has loaded properly
• Research whether we should assigning a size to the html element and using rem for font sizing
• Explore typefaces that expand the system's expressive gamut
