TRACKER: Lighthouse/a11y report fixes

[tiffehr]

• TypeKit: "Consider setting font-display to swap or optional to ensure text is consistently visible. swap can be further optimized to mitigate layout shifts with font metric overrides."
  • see TRACKER: Audit and standardize Typekit kits across SRCCON repos (freight/sofia && tisa/sofia combos) #425 as more explicit example about upgrading existing TypeKit collections
• Performance: "Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity."
  • We should consider dropping out-of-date or little used layout: options, unless we decide to reboot them
• Accessibility: "Background and foreground colors do not have a sufficient contrast ratio"
  • it doesn't like our orange #fc6e1f
• Accessibility: "Heading elements are not in a sequentially-descending order"
  • homepage.md our styles are tied to heading sizes not classes, we should move the styles to a class-based rule
