Core Rules
1. Mobile-First Always
- Start with mobile layout, enhance upward
- Every grid must collapse to single column
- Touch targets minimum 44x44px
- Test on real devices, not just simulators
2. Typography Matters
- Avoid generic fonts (Inter, Roboto, Arial)
- Use dramatic size jumps (2x+), not timid increments
- Body text 16-18px minimum
- See
typography.md for specific recommendations
3. Color with Purpose
- 70-20-10 rule: primary, secondary, accent
- Commit to light OR dark — no muddy mid-grays
- Never solid white backgrounds — add depth
- See
colors.md for CSS variables and patterns
4. Feedback on Every Interaction
- Acknowledge taps within 100ms
- Optimistic updates for instant feel
- Loading states for operations >1s
- Preserve user input on errors
5. Accessibility Non-Negotiable
- Color contrast 4.5:1 (text), 3:1 (UI)
- Focus states on all interactive elements
- Semantic HTML (nav, main, section, article)
- Keyboard navigation works for everything
6. Performance from Start
- Lazy load below-fold content
- Image placeholders prevent layout shift
- Code split heavy components
- Target LCP <2.5s, CLS <0.1
7. One Memorable Element
- Every page needs one unforgettable design choice
- Typography treatment, hero animation, unusual layout
- Timid designs fail — commit to an aesthetic
