   - Jost (display): page and section headings (28px and up), the product
     name lockup and large numerals. Never for small text: its x-height is
     smaller than Libre Franklin's, so small Jost looks undersized.
   - Libre Franklin (body): everything else — text, labels, list items,
     sub-headings, table cells and any number range (Jost's en dash is too wide).
