 ## Text Button
 
+**Note**: Our text buttons use bold formatting to differentiate themselves from normal text, as color alone does not meet the 3:1 contrast ratio required for accessibility. However, bold formatting may not be sufficient in all contexts, such as when placed alongside a bold heading.
