"Make it look nice"

✅ ชัดเจน:
"Use a clean minimal design with:
- Soft shadows on cards
- Rounded corners (8px)
- Blue (#3B82F6) as primary color
- White background
- Gray text for secondary info"

3. Define User Flow

"When user signs up:
1. Show welcome modal
2. Guide through creating first project
3. Show sample project as template
4. Redirect to dashboard

Dashboard shows:
- Quick actions at top
- Recent projects
- Usage stats"

4. Specify Data Structure

"Each task should have:
- Title (required)
- Description (optional)
