Key Decisions
Zustand over Redux
Decision: Zustand for state management.
Reasoning:
- Simpler API, less boilerplate
- Better TypeScript integration
- Smaller bundle size
- Perfect for e-commerce state (cart, wishlist, theme)
Design Tokens
Decision: Custom design token system over raw Tailwind.
Reasoning:
- Easy theming for buyers
- Consistent spacing, colors, typography
- One config file to customize entire look
Comprehensive Testing
Decision: 48+ unit tests + E2E + Storybook.
Reasoning:
- Buyers expect quality
- Tests document expected behavior
- Storybook serves as component documentation
