Building a Nostalgic 8-bit Universe with Modern Tech: A Vibe Coding Journey

A developer rebuilt their portfolio with an 8-bit retro aesthetic using a 95% AI-driven workflow governed by strict design constraints. The project implements custom pixel mask transitions using Bayer dithering, a singleton PixelationManager for Canvas optimization, and adaptive WebGL quality scaling to maintain 60 FPS. Key techniques include a .cursorrules "Design Constitution" that prevents AI from hardcoding values, atomic component development in Storybook, GSAP ScrollTrigger orchestration, and performance optimizations like offscreen canvas rendering and intersection observers. The approach demonstrates how to maintain design integrity and code quality while leveraging AI for rapid development.
