Debug and fix bugs. Run through the UI and fix every bug you find, using React DevTools, the Profiler, the Network tab, and strategic logs. A polished UI starts with no known bugs.
In the finishing phase. Add semantic HTML, accessible names, keyboard navigation, focus management for modals, sufficient color contrast, and test with a screen reader. Accessibility is part of polishing, not an afterthought.
After bugs are fixed and states handled. Measure with the Profiler, stabilize references, wrap with React.memo where needed, virtualize long lists, lazy-load images, code split routes, and debounce inputs. Measure again to confirm each fix helps.
