Revamp React Next.js UI

I already have a React + Next.js application in production, but the interface feels dated and some screens are beginning to creak under heavier traffic. I want to refresh the look, tighten the user flows, and squeeze a little more speed out of every render.

Here is what I’m after:
• A complete visual design update—new color scheme, cleaner typography, and a more balanced layout that stays consistent across desktop, tablet, and mobile.
• Tangible usability enhancements: clearer affordances, improved form interactions, and accessible navigation that meets WCAG basics.
• Lightweight performance optimizations. I’m thinking component-level refactors, smarter data fetching with React Query or SWR, and judicious code-splitting to cut initial bundle size.

Everything lives in a private GitHub repo and is already set up with TypeScript, styled-components, and Storybook. I’ll grant you a feature branch; I’m happy to review work in small PRs as we go. Final acceptance will be based on:

• Updated UI matching agreed Figma frames
• Lighthouse score improvement (desktop + mobile)
• No regression on existing Jest & Cypress tests

If you have a sharp eye for design and can move comfortably inside a Next.js codebase, I’d love to collaborate and ship this refresh quickly.
