Guidelines:

• Component names: Use PascalCase as they appear in imports (Avatar, ButtonIcon, SearchField)
• Multiple components: Affected components: Button, ButtonLink, ButtonIcon
• General changes: Omit the metadata line (build changes, package-level updates)
• Placement: The line can appear anywhere in the description
