Summary

Added vertical breathing room between the stacked token links on the Font size and family utility page, so the links meet WCAG's minimum touch-target spacing.

Closes #2796

Problem statement

In the "Palette contents" column on the Font size and family page, token links stack vertically in 21 groups. Each link is a tap target about 22px tall with under 2px of space to the next one — failing WCAG 2.5.8 (Target Size Minimum), which needs adjacent targets to reach a 24px pitch. On a phone, tapping the right token was a coin flip.

Solution

Added the smallest standard USWDS spacing utility (margin-bottom-05, 4px) to each stacked row in _includes/utilities/typescale-palettes.html. That takes the row pitch from about 24px to about 28px — comfortably past the requirement without visually changing the table's character. The global token-link style was deliberately left alone: the issue notes other token usages around the site aren't affected, and a repo check confirmed this include is the only place with the stacked pattern.

Testing and review

• The diff is exactly 21 lines, each adding only the spacing class; rendered page verified showing all 21 spaced rows.
• bundle exec rspec passes (10 examples, 0 failures).
• To review: open Utilities → Font size and family and look at the "Palette contents" column — the stacked token links now have a small, even gap.
