This is for when your app works but looks merely okay and you want to push it to Stripe-level visual quality. The core insight is running the same polish prompt 10+ times rather than making one big pass, because small improvements compound dramatically. It treats desktop and mobile as separate optimization problems instead of compromising both, includes Tailwind implementations for glassmorphism and bento grids, and has solid WCAG 2.2 AA guidance. The common mistakes section is honest about what breaks this approach: don't polish broken apps, don't skip iterations when changes seem minimal, and always add accessibility borders to neumorphic designs. Best used after your design system exists and bugs are fixed.
