Add light theme to website

Our current aesthetic is dark, minimal, and premium (Midnight Navy canvas, Off-White typography, Champagne Gold accents). We need a fresh visual flow on the landing page that converts better, along with a smooth, dynamic Light/Dark Theme Toggle across the web app. Scope of Work: Landing Page Redesign: Redesign the current landing page to feel sleek, modern, direct, and high-converting. Clear visual hierarchy with strong hero messaging, feature breakdowns, and CTA placement. Mobile-first responsive optimization (our user base is ~80% mobile). Light/Dark Mode Implementation: Build a smooth theme toggle (Light / Dark mode switcher). Map our existing brand colors to a clean, high-contrast light theme palette while keeping our premium aesthetic intact (Champagne Gold accents, crisp typography). Ensure user theme preference persists across sessions. Requirements: Proven track record designing & building high-converting landing pages for modern tech/SaaS platforms. Strong expertise in responsive design and clean theme state management (CSS variables / Tailwind / React state). Experience with clean design systems (bento grid layouts, subtle micro-interactions, pill badges, sharp typography). Portfolio showing modern, minimalist, dark & light theme web projects.
