.claude/skills/ui/SKILL.md:14

• This skill was renamed to /ui, but the document title still says # Frontend, which makes the skill name/branding inconsistent and may confuse anyone scanning the skill docs. Consider updating the heading (and any surrounding wording) to match the new /ui name while keeping the external frontend-design guideline link as-is.
