+
+#### 1.3-1.6 Additional Vercel Resources
+**Font System (Geist)**: Scientific approach to typography for optimal screen reading
+**Rendering & Performance**: Framework-defined infrastructure for optimal user experience
+**Web Apps Solutions**: Systematic approaches to modern web application architecture
+
+### 2. Radix UI Ecosystem (5 Resources)
+
+#### 2.1 Radix UI Colors - Scientific Color Theory
+**Revolutionary Approach:**
+- **12-Step Color Scales**: Based on human perception science, not aesthetic preference
+- **Semantic Naming**: Colors named by function (background, border, text) not appearance
+- **Automatic Dark Mode**: Light/dark pairs scientifically calibrated for accessibility
+- **APCA Contrast**: Uses modern contrast algorithm for accurate visual perception
+
+**Color Scale System:**
+```css
+/* Semantic Usage Example */
+--color-app-bg: var(--gray-1);      /* App background */
+--color-subtle-bg: var(--gray-2);   /* Subtle background */
+--color-ui-element: var(--gray-3);  /* UI element background */
+--color-hovered: var(--gray-4);     /* Hovered UI element */
+--color-active: var(--gray-5);      /* Active UI element */
+--color-borders: var(--gray-6);     /* Subtle borders */
+--color-solid: var(--gray-9);       /* Solid backgrounds */
+--color-text-high: var(--gray-12);  /* High-contrast text */
+```
+
+#### 2.2 Radix UI Primitives - Unstyled Component Architecture
+**Key Principles:**
+- **Behavior Without Opinions**: Unstyled components provide functionality, not visuals
+- **Accessibility Built-In**: WCAG compliance, ARIA attributes, keyboard navigation included
+- **Compound Components**: Related components work together seamlessly
+- **Polymorphic Design**: Components adapt to different HTML contexts via `asChild` prop
+
+**Implementation Pattern:**
+```tsx
+// Compound Component Pattern
+<Dialog.Root>
+  <Dialog.Trigger asChild>
+    <Button>Open Dialog</Button>
+  </Dialog.Trigger>
+  <Dialog.Portal>
+    <Dialog.Overlay />
+    <Dialog.Content>
+      <Dialog.Title>Title</Dialog.Title>
+      <Dialog.Close />
+    </Dialog.Content>
+  </Dialog.Portal>
+</Dialog.Root>
+```
+
+#### 2.3-2.5 Radix UI Complete Ecosystem
+**Icons**: 318 consistent icons with accessibility attributes
+**Website Implementation**: Real-world patterns and best practices
+**Themes**: Complete design system with responsive utilities
+
+### 3. Storybook Documentation Methodology (1 Resource)
+
+#### Component-Driven Development Philosophy

+- **Interactive Examples**: Stories demonstrate all component states and variations
+- **Visual Testing**: Automated regression testing capabilities
+
+**Storybook Benefits for Design Systems:**
+1. **Story-Based Documentation**: Each component variation documented as a "story"
+2. **Cross-Team Communication**: Shared reference between design and development
+3. **Quality Assurance**: Documentation enforces consistent component usage
+4. **Accessibility Testing**: Built-in tools for accessibility validation
+
+**Implementation in CodeStorm Hub:**

+- **Utility Composition**: Complex styles built from simple, reusable utilities
+- **Design Token System**: Centralized values ensure consistency
+- **8px Grid System**: Systematic spacing prevents arbitrary decisions
+- **Modular Scales**: Typography and sizing follow mathematical progressions
+
+**Constraint Benefits:**
+- More consistent systems than unlimited creative freedom
+- Faster development through utility composition
+- Better maintainability through systematic approach
+- Reduced CSS bundle size through utility reuse
+
+### 5. GitHub Resources Analysis (2 Resources)
