The quick brown fox jumps over the lazy dog. This paragraph is in standard body text size (16px), the threshold WCAG uses for normal-text contrast requirements.

Smaller secondary text — captions, footnotes, and metadata often use this size. Same contrast rules apply unless the content is decorative or part of a logo.
