Use this skill for chart and responsive-debug work inside frontend/.
Workflow
- Start from the page or component that is visibly wrong.
- Trace whether the problem comes from page layout, chart container sizing, tooltip styling, or label rendering.
- Check mobile and dark mode behavior before finalizing.
- Prefer changes that improve the shared chart system rather than patching a single chart unnecessarily.
