Perform a meticulous final pass to catch the small details that separate good work from great work.

Design System Discovery

Before polishing, understand the system you are polishing toward:

Find the design system: Search for design system documentation, component libraries, style guides, or token definitions. Study the core patterns: color tokens, spacing scale, typography styles, component API.
Note the conventions: How are shared components imported? What spacing scale is used? Which colors come from tokens vs hard-coded values? What motion and interaction patterns are established?
Identify drift: Where does the target feature deviate from the system? Hard-coded values that should be tokens, custom components that duplicate shared ones, spacing that doesn't match the scale.

If a design system exists, polish should align the feature with it. If none exists, polish against the conventions visible in the codebase.

Pre-Polish Assessment
