Background: warm-cream (#fef3c7, #fef9c3)
Gradients:  Smooth transitions for visual interest

Typography

Hierarchy: h1 > h2 > h3 > p (clear distinction)
Body text: 16px+ for readability
Line-height: Consistent spacing
Hero sections: Center-aligned

Approach: Mobile-first responsive
Spacing: Tailwind utilities (p-4, gap-6, etc.)
Animations: Framer Motion (smooth, not jarring)

Workflow

1. Analyze Current Design

Issues Checklist:
- [ ] Color consistency problems?
- [ ] Layout/alignment issues?
- [ ] Typography hierarchy unclear?
- [ ] Spacing inconsistent?
- [ ] Responsive breakpoints broken?
- [ ] Animations missing/excessive?

2. Propose Improvements (CARIO)

📋 Context:
  - Page: [Home/Projects/About/Speaking]
  - Current state: [description]
  - Issue: [what looks bad]

❓ Problems:
  1. [Color inconsistency]
  2. [Poor spacing]
  3. [Weak hierarchy]

🎯 Options:
  A. Minor tweaks (15 min, low impact)
  B. Moderate redesign (30-45 min, medium impact)
  C. Major overhaul (1-2 hours, high impact)

💡 Recommendation: [Option B]
  - Changes: [color X→Y, spacing p-4→p-6, add gradient]
  - Reasoning: [balances improvement vs time]

⚡ Impact:
  - Files: [list]
  - Testing: [responsive + visual]

3. Get User Confirmation

4. Implement Changes

Checklist:

• [ ] Update Tailwind classes
• [ ] Ensure responsive (sm:, md:, lg: breakpoints)
• [ ] Add/update Framer Motion animations
• [ ] Maintain color palette
• [ ] Follow typography hierarchy

Example:

// Before
<div className="p-4 bg-white">
  <h1 className="text-2xl">Title</h1>
</div>

// After

    Title
  </h1>
</div>

5. Test Responsive Design

npm run dev
# Test at: Mobile (375px), Tablet (768px), Desktop (1280px)

Visual checklist:

• [ ] Mobile (< 640px): Readable, no overflow
• [ ] Tablet (640-1024px): Proper spacing
• [ ] Desktop (> 1024px): Optimal layout
• [ ] Animations: Smooth (60fps)

6. Commit and Deploy

npm run build  # Verify
git add .
git commit -m "style: improve [page] design with better spacing and colors"
