+# Apple-Style Design Optimization - Complete Summary
+
+## Overview
+
+This document details the comprehensive frontend optimization based on Airtable's functionality with Apple's design language (苹果风格). The implementation focuses on creating a refined, minimal, and highly polished user experience that embodies Apple's design principles.
+
+## Design Philosophy
+
+The optimization follows Apple's core design principles:
+
+1. **Clarity** - Clear typography, refined spacing, and visual hierarchy
+2. **Deference** - Content is paramount; UI elements don't compete for attention
+3. **Depth** - Subtle shadows and layers create realistic depth
+4. **Consistency** - Uniform design language across all components
+5. **Attention to Detail** - Refined micro-interactions and smooth transitions
+
+## Key Changes
+
+### 1. Design System Foundation
+
+#### Color Palette

+
+## Migration Guide
+
+### For Developers
+
+The changes are backward compatible. Existing code will continue to work with the new design system.
+
+To adopt new features:
+
+```tsx
+// Use new tinted button variant
+<Button variant="tinted">Action</Button>
+
+// Components automatically use new styles
+<Input placeholder="Search..." />
+<Modal isOpen={true} title="Settings">...</Modal>
+```
+
+### CSS Classes
+
+New utility classes available:
+
+```css
+.transition-apple       /* Apple-style transitions */
+.backdrop-blur-apple    /* macOS-style backdrop blur */
+.text-render-optimized  /* Optimized text rendering */
+```
+
+## Design Tokens
+
+```css
+:root {
+  --radius: 0.5rem;           /* 8px base radius */
+  --primary: 217 91% 60%;     /* Blue-600 */
+  --border: 0 0% 90%;         /* Gray-200 */
+  --ring: 217 91% 60%;        /* Blue-600 */

+```
+
+## Conclusion
+
+This optimization brings ObjectQL's UI in line with modern design standards, specifically embodying Apple's design language.
