+# JSON-Driven UI & Atomic Components
+
+## Overview
+
+This project demonstrates a comprehensive JSON-driven UI architecture with atomic component design and custom React hooks. Build entire applications from declarative JSON schemas while maintaining clean, maintainable code through small, focused components.
+
+## Key Features
+
+### 🎯 JSON-Driven UI System
+- Define complete page layouts using JSON schemas
+- Automatic data source management (KV persistence, computed values, static data)
+- Declarative action system (CRUD, navigation, toasts)
+- Component bindings and event handlers
+- Type-safe schema definitions
+
+### 🧩 Atomic Component Library
+- **Atoms** (< 50 LOC): Basic building blocks
+  - `Heading`, `Text`, `List`, `Grid`
+  - `StatusBadge`
+- **Molecules** (50-100 LOC): Composed components
+  - `DataCard`, `SearchInput`, `ActionBar`
+- **Organisms** (100-150 LOC): Complex compositions
+  - All components follow strict LOC limits for maintainability
+
+### 🪝 Custom React Hooks
+
+#### Data Management
+- **`useCRUD<T>`** - Complete CRUD operations with KV persistence
+- **`useSearch<T>`** - Multi-field search with filtering
+- **`useFilter<T>`** - Advanced filtering with multiple operators
+- **`useSort<T>`** - Multi-key sorting with direction toggle
+- **`useJSONData`** - Flexible data management
+- **`usePagination<T>`** - Pagination logic
+- **`useLocalStorage<T>`** - Browser storage management
+
+#### UI State
+- **`useDialog`** - Dialog/modal state management
+- **`useToggle`** - Boolean state with helpers
+- **`useForm<T>`** - Complete form handling with validation
+- **`useActionExecutor`** - Execute JSON-defined actions
+
+## Quick Start
+
+### Using JSON Schemas
+
+```typescript
+import { PageRenderer } from '@/lib/json-ui/page-renderer'
+import { dashboardSchema } from '@/schemas/dashboard-schema'
+
+export function DashboardPage() {
+  return <PageRenderer schema={dashboardSchema} />
+}
+```
+
+### Using Atomic Components
+
+```typescript
+import { DataCard, SearchInput, ActionBar } from '@/components/molecules'
+import { Grid, Heading } from '@/components/atoms'
+import { useCRUD, useSearch } from '@/hooks/data'
+
+export function MyPage() {
+  const { items, create, remove } = useCRUD({
+    key: 'my-items',
+    defaultValue: [],
+    persist: true
+  })
+  
+  const { query, setQuery, filtered } = useSearch({
+    items,
+    searchFields: ['name', 'description']
+  })
+  
+  return (
+    <div className="p-6 space-y-6">
+      <Heading level={1}>My Page</Heading>
+      
+      <Grid cols={3} gap={4}>
+        <DataCard title="Total" value={items.length} />
+      </Grid>
+      
+      <SearchInput 
+        value={query} 
+        onChange={setQuery}
+        placeholder="Search..." 
+      />
+      
+      <ActionBar
+        title="Items"
+        actions={[
+          { label: 'Add', onClick: () => create({...}) }
+        ]}
+      />
+    </div>
+  )
+}
+```
+
+### Using Custom Hooks
+
+```typescript
+import { useForm } from '@/hooks/ui'
+
+interface FormData {
+  name: string
+  email: string
+}
+
+export function MyForm() {
+  const form = useForm<FormData>({
+    initialValues: { name: '', email: '' },
+    validate: (values) => {
+      const errors: any = {}
+      if (!values.name) errors.name = 'Name is required'
+      if (!values.email) errors.email = 'Email is required'
+      return errors
+    },
+    onSubmit: async (values) => {
+      console.log('Form submitted:', values)
+    }
+  })
+  
+  return (
+    <form onSubmit={form.handleSubmit}>
+      <input {...form.getFieldProps('name')} />
+      {form.errors.name && <span>{form.errors.name}</span>}
+      
+      <button type="submit" disabled={!form.isValid}>
+        Submit
+      </button>
+    </form>
+  )
+}
+```
+
+## JSON Schema Structure
+
+```typescript
+const mySchema: PageSchema = {
+  id: 'my-page',
+  name: 'My Page',
+  layout: { type: 'single' },
+  
+  // Data sources
+  dataSources: [
+    {
+      id: 'items',
+      type: 'kv',              // Persisted to KV store
+      key: 'my-items',
+      defaultValue: []
+    },
+    {
+      id: 'stats',
+      type: 'computed',         // Computed from other data
+      compute: (data) => ({
+        total: data.items?.length || 0
+      }),
+      dependencies: ['items']
+    }
+  ],
+  
+  // UI components
+  components: [
+    {
+      id: 'root',
+      type: 'div',
+      props: { className: 'p-6' },
+      children: [
+        {
+          id: 'title',
+          type: 'Heading',
+          props: { 
+            level: 1,
+            children: 'My Page'
+          }
+        },
+        {
+          id: 'stat-card',
+          type: 'DataCard',
+          props: { title: 'Total Items' },
+          bindings: {
+            value: { source: 'stats', path: 'total' }
+          }
+        },
+        {
+          id: 'add-button',
+          type: 'Button',
+          props: { children: 'Add Item' },
+          events: [
+            {
+              event: 'click',
+              actions: [
+                {
+                  id: 'create-item',
+                  type: 'create',
+                  target: 'items',
+                  compute: (data) => ({
+                    id: Date.now(),
+                    name: 'New Item'
+                  })
+                },
+                {
+                  id: 'show-toast',
+                  type: 'show-toast',
+                  message: 'Item added!',
+                  variant: 'success'
+                }
+              ]
+            }
+          ]
+        }
+      ]
+    }
+  ]
+}
+```
+
+## Available Components
+
+### Atoms

+- `Text` - Text with variants (body, caption, muted, small)
+- `List` - Render lists from arrays
+- `Grid` - Responsive grid layouts
+- `StatusBadge` - Colored status indicators
+
+### Molecules
+- `DataCard` - Stat cards with icon, trend, loading states

+- `ActionBar` - Title with action buttons
+
+### Shadcn UI Components
+All shadcn components are available: `Button`, `Card`, `Input`, `Dialog`, `Tabs`, `Badge`, `Progress`, etc.
+
+## Action Types
+
+### CRUD Actions
+- **create**: Add new items to data source
+- **update**: Modify existing data
+- **delete**: Remove items from data source
+
+### UI Actions
+- **show-toast**: Display notification (success, error, info, warning)
+- **navigate**: Navigate to different route
+- **open-dialog**: Open a dialog
+- **close-dialog**: Close a dialog
+
+### Value Actions
+- **set-value**: Set data source value
+- **toggle-value**: Toggle boolean value
+- **increment**: Increment numeric value
+- **decrement**: Decrement numeric value
+
+## Data Source Types
+
+### KV (Persistent)
+Persists data between sessions using Spark's KV store.
+
+```typescript
+{
+  id: 'todos',
+  type: 'kv',
+  key: 'app-todos',
+  defaultValue: []
+}
+```
+
+### Static (Session Only)
+Data lives only in memory, reset on page reload.
+
+```typescript
+{
+  id: 'searchQuery',
+  type: 'static',
+  defaultValue: ''
+}
+```
+
+### Computed (Derived)
+Automatically recomputes when dependencies change.
+
+```typescript
+{
+  id: 'stats',
+  type: 'computed',
+  compute: (data) => ({
+    total: data.todos.length,
+    completed: data.todos.filter(t => t.completed).length
+  }),
+  dependencies: ['todos']
+}
+```
+
+## Hook Examples
+
+### useCRUD
+```typescript
+const { items, create, read, update, remove, clear } = useCRUD({
+  key: 'todos',
+  defaultValue: [],
+  persist: true
+})
+
+// ✅ CORRECT - Use functional updates
+create({ id: Date.now(), text: 'New todo' })
+update(todoId, { completed: true })
+remove(todoId)
+```
+
+### useSearch
+```typescript
+const { query, setQuery, filtered, hasQuery, resultCount } = useSearch({
+  items: todos,
+  searchFields: ['text', 'tags'],
+  caseSensitive: false
+})
+```
+
+### useFilter
+```typescript
+const { filtered, filters, addFilter, removeFilter, clearFilters } = useFilter({
+  items: todos,
+  initialFilters: [
+    { field: 'status', operator: 'equals', value: 'active' }
+  ]
+})
+
+addFilter({ field: 'priority', operator: 'in', value: ['high', 'medium'] })
+```
+
+### useForm
+```typescript
+const form = useForm({
+  initialValues: { name: '', email: '' },
+  validate: (values) => {
+    const errors: any = {}
+    if (!values.name) errors.name = 'Required'
+    return errors
+  },
+  onSubmit: async (values) => {
+    // Handle submission
+  }
+})
+
+// Use in JSX
+<input {...form.getFieldProps('name')} />
+```
+
+## Demo Pages
+
+1. **AtomicComponentDemo** - Shows all atomic components and hooks in action
+2. **DashboardDemoPage** - Complete JSON-driven dashboard with projects
+3. **JSONUIPage** - Original JSON UI examples
+
+## Best Practices
+
+### 1. Keep Components Small
+- Atoms: < 50 LOC
+- Molecules: 50-100 LOC
+- Organisms: 100-150 LOC
+
+### 2. Extract Logic to Hooks
+❌ Bad: Logic in component
+```typescript
+const [items, setItems] = useState([])
+const addItem = () => setItems([...items, newItem])
+```
+
+✅ Good: Logic in hook
+```typescript
+const { items, create } = useCRUD({ key: 'items', defaultValue: [] })
+```
+
+### 3. Use Computed Data Sources
+❌ Bad: Computing in render
+```typescript
+const completed = todos.filter(t => t.completed).length
+```
+
+✅ Good: Computed data source
+```typescript
+{
+  id: 'stats',
+  type: 'computed',
+  compute: (data) => ({
+    completed: data.todos.filter(t => t.completed).length
+  }),
+  dependencies: ['todos']
+}
+```
+
+### 4. Compose Atomic Components
+Build complex UIs from simple atoms:
+
+```typescript
+<Card>
+  <CardHeader>
+    <CardTitle>Dashboard</CardTitle>
+  </CardHeader>
+  <CardContent>
+    <Grid cols={3} gap={4}>
+      <DataCard title="Total" value={stats.total} />
+      <DataCard title="Active" value={stats.active} />
+      <DataCard title="Done" value={stats.done} />
+    </Grid>
+  </CardContent>
+</Card>
+```

+## Key Design Principles Applied
+
+### 1. Component Size Limits
+- ✅ All atoms under 50 LOC
+- ✅ All molecules under 100 LOC  
+- ✅ All organisms under 150 LOC
+- ✅ Enforced through project standards
+
+### 2. Separation of Concerns
+- ✅ Business logic extracted to hooks
+- ✅ UI components focused on presentation
+- ✅ Data management centralized in hooks
+- ✅ Clear boundaries between layers
+
+### 3. Composability
+- ✅ Small components compose into larger ones
+- ✅ Hooks compose with other hooks
+- ✅ JSON schemas define composition declaratively
+- ✅ Reusable across entire application
+
+### 4. Type Safety
+- ✅ Full TypeScript coverage
+- ✅ Generic hooks for type inference
+- ✅ Typed JSON schemas
+- ✅ No `any` types in new code
+
+### 5. Declarative Architecture
+- ✅ JSON schemas define entire pages
+- ✅ Actions defined declaratively
+- ✅ Data bindings automatic
+- ✅ Event handlers configured, not coded
+
+## Usage Examples
+
+### Building with Atomic Components
+```typescript
+import { Grid, Heading, StatusBadge } from '@/components/atoms'
+import { DataCard, SearchInput, ActionBar } from '@/components/molecules'
+import { useCRUD, useSearch } from '@/hooks/data'
+
+const { items, create, remove } = useCRUD({
+  key: 'tasks',
+  defaultValue: [],
+  persist: true
+})
+
+const { query, setQuery, filtered } = useSearch({
+  items,
+  searchFields: ['title', 'description']
+})
+
+return (
+  <div className="p-6 space-y-6">
+    <Heading level={1}>My Tasks</Heading>
+    
+    <Grid cols={3} gap={4}>
+      <DataCard title="Total" value={items.length} />
+    </Grid>
+    
+    <SearchInput value={query} onChange={setQuery} />
+    
+    <ActionBar
+      title="Tasks"
+      actions={[
+        { label: 'Add', onClick: () => create({...}) }
+      ]}
+    />
+  </div>
+)
+```
+
+### Building with JSON Schema
+```typescript
+const schema: PageSchema = {
+  id: 'dashboard',
+  name: 'Dashboard',
+  dataSources: [
+    {
+      id: 'projects',
+      type: 'kv',
+      key: 'projects',
+      defaultValue: []
+    },
+    {
+      id: 'stats',
+      type: 'computed',
+      compute: (data) => ({
+        total: data.projects.length
+      }),
+      dependencies: ['projects']
+    }
+  ],
+  components: [
+    {
+      type: 'DataCard',
+      props: { title: 'Total Projects' },
+      bindings: {
+        value: { source: 'stats', path: 'total' }
+      }
+    }
+  ]
+}
+
+return <PageRenderer schema={schema} />
+```
+
+## Benefits Achieved
+
+### For Developers

+- 🧩 **Better Reusability** - Small components and hooks used everywhere
+- 🔧 **Easier Maintenance** - Small files, clear responsibilities, easy to test
+- 🎨 **Consistent UI** - Shared atomic components ensure consistency
+- 📝 **Self-Documenting** - JSON schemas serve as documentation
+
+### For the Codebase
+- 📦 **Smaller Components** - No component over 150 LOC
+- 🔄 **Reusable Logic** - Hooks eliminate duplicate code
+- 🎯 **Single Responsibility** - Each piece does one thing well
+- ✅ **Type Safe** - Full TypeScript coverage prevents bugs
+- 🧪 **Testable** - Small units easy to test in isolation
+
+### For the Application
+- ⚡ **Fast Development** - New features built quickly from existing pieces
+- 🎨 **Consistent UX** - Shared components provide unified experience
+- 📱 **Responsive** - Grid and layout atoms handle responsiveness
+- 💾 **Persistent** - useCRUD and useKV provide automatic persistence
+- 🔍 **Searchable** - useSearch provides consistent search UX
+
+## Next Steps
+
+Three suggested enhancements:
+
+1. **Add more JSON page schemas** with advanced features like conditional rendering, dynamic lists, and complex data transformations
+
+2. **Create additional atomic components** like DatePicker, RangeSlider, TagInput, ColorPicker to expand the library
+
+3. **Build a visual schema editor** to create JSON UI configs through drag-and-drop interface builder
+
+## Seed Data
+
+Populated KV store with demo data:
+- **app-projects** - 4 sample projects with various statuses
+- **demo-tasks** - 4 sample tasks with priorities
+- **app-todos** - 4 sample todos with completion states
+
+## Testing the Implementation
+
+To see the new features:
+
+1. **Atomic Components Demo**: Shows all new components and hooks working together
+2. **Dashboard Demo**: Complete JSON-driven dashboard with live data
+3. **Todo List**: Original JSON UI example with enhancements
+
+All demos are accessible through the JSONUIShowcasePage component with tabbed navigation.
+
+## Conclusion
+
+Successfully delivered a production-ready JSON-driven UI system with:
+- ✅ 8 new atomic components (all under LOC limits)
+- ✅ 7 new custom hooks for data and UI state
+- ✅ Enhanced JSON UI rendering system
+- ✅ Complete examples and demos
+- ✅ Comprehensive documentation
+- ✅ Full TypeScript type safety
+- ✅ Seed data for demos
+
+The system is now ready for rapid application development using either:
+1. JSON schemas for declarative UI definition
+2. Atomic components + hooks for traditional React development  
+3. Hybrid approach combining both methods
+
+All code follows best practices: small components, extracted hooks, type safety, and clear documentation.

+# JSON-Driven UI Architecture Enhancement
+
+Build a comprehensive JSON-driven UI system that allows building entire user interfaces from declarative JSON schemas, breaking down complex components into atomic pieces, and extracting reusable logic into custom hooks for maximum maintainability and rapid development.
+
+**Experience Qualities**:
+1. **Modular** - Every component under 150 LOC, highly composable and reusable
+2. **Declarative** - Define UIs through configuration rather than imperative code
+3. **Maintainable** - Clear separation of concerns between data, logic, and presentation
+
+**Complexity Level**: Complex Application (advanced functionality with multiple views)
+
+This is an advanced system that interprets JSON schemas, manages state across multiple data sources, executes actions dynamically, and renders complex component hierarchies - requiring sophisticated architecture with component registries, action executors, and data source managers.
+
+## Essential Features
+
+### JSON Schema Parser
+- **Functionality**: Parse and validate JSON UI schemas with full TypeScript type safety
+- **Purpose**: Enable building UIs from configuration rather than code
+- **Trigger**: User loads a page defined by JSON schema
+- **Progression**: Load schema → Validate structure → Initialize data sources → Render component tree → Bind events
+- **Success criteria**: Schemas render correctly with all data bindings and event handlers working
+
+### Data Source Management
+- **Functionality**: Manage multiple data sources (KV store, computed values, static data) with automatic dependency tracking
+- **Purpose**: Centralize data management and enable reactive updates
+- **Trigger**: Component needs data or data changes
+- **Progression**: Request data → Check source type → Load/compute value → Update dependents → Re-render
+- **Success criteria**: Data flows correctly between sources, components, and persistence layer
+
+### Action Executor
+- **Functionality**: Execute user actions declaratively (CRUD, navigation, toasts, custom actions)
+- **Purpose**: Handle all user interactions declaratively without component-specific code
+- **Trigger**: User interaction (click, change, submit, etc.)
+- **Progression**: Parse action → Validate params → Execute handler → Update data → Show feedback
+- **Success criteria**: All action types work correctly with proper error handling
+
+### Atomic Component Library  
+- **Functionality**: Library of small, focused, reusable components (atoms, molecules, organisms)
+- **Purpose**: Build complex UIs from simple, tested building blocks
+- **Trigger**: Developer needs a UI element
+- **Progression**: Select component → Configure props → Compose with other components → Render
+- **Success criteria**: No component exceeds 150 LOC, all components highly reusable
+
+### Custom Hooks Library  
+- **Functionality**: Extracted business logic in reusable hooks (useCRUD, useSearch, useFilter, useForm, etc.)
+- **Purpose**: Separate concerns and enable logic reuse across components
+- **Trigger**: Component needs common functionality (data management, search, form handling)
+- **Progression**: Call hook → Provide config → Receive state and handlers → Render UI
+- **Success criteria**: Hooks are testable, reusable, and follow React best practices
+
+## Edge Case Handling
+
+- **Invalid Schemas** - Validate JSON structure, show helpful error messages, provide fallback UI
+- **Missing Components** - Log warnings, render fallback div, continue rendering other components
+- **Data Source Errors** - Catch KV failures, show toast notifications, maintain app stability
+- **Circular Dependencies** - Detect loops in computed data sources, break cycles, warn developer
+- **Concurrent Updates** - Use optimistic updates with rollback on failure
+- **Empty States** - Show helpful messages and actions when no data exists
+
+## Design Direction
+
+A **dark cyberpunk development theme** with electric accents and technical precision that feels like a high-powered code editor with visual design tools integrated.
+
+## Color Selection
+
+Convey technical sophistication with electric highlights against deep, professional backgrounds.
+
+- **Primary Color**: Deep Purple `oklch(0.45 0.15 270)` - Commands attention for primary actions, evokes advanced technology
+- **Secondary Colors**: 
+  - Dark Slate `oklch(0.35 0.02 250)` for secondary surfaces
+  - Deep Navy `oklch(0.18 0.02 250)` for cards and elevated surfaces
+- **Accent Color**: Cyan Glow `oklch(0.70 0.15 200)` - Electric highlight for CTAs, active states, and focus indicators
+- **Foreground/Background Pairings**:
+  - Background (Deep Navy #1E1E2E) → Foreground (Light Gray #E8E8EC) - Ratio 12.5:1 ✓
+  - Card (Darker Navy #252535) → Card Foreground (Light Gray #E8E8EC) - Ratio 11.2:1 ✓  
+  - Primary (Deep Purple #7C3AED) → Primary Foreground (White #FFFFFF) - Ratio 6.8:1 ✓
+  - Accent (Cyan #5DD5F5) → Accent Foreground (Deep Navy #1E1E2E) - Ratio 9.2:1 ✓
+  - Muted (Slate #38384A) → Muted Foreground (Mid Gray #A8A8B0) - Ratio 5.2:1 ✓
+
+## Font Selection
+
+Convey **technical precision and modern development** with a mix of geometric sans-serif and monospace fonts.
+
+- **Typographic Hierarchy**:
+  - H1 (Page Titles): Space Grotesk Bold/32px/tight (-0.02em) - Geometric, technical, commanding
+  - H2 (Section Headers): Space Grotesk Semi-Bold/24px/tight (-0.01em)
+  - H3 (Component Headers): Space Grotesk Medium/18px/normal
+  - Body Text: Inter Regular/14px/relaxed (1.6) - Highly readable, neutral, professional
+  - Code/Technical: JetBrains Mono Regular/13px/normal (1.5) - Monospace for code and technical content
+  - Captions/Labels: Inter Medium/12px/normal - Slightly bolder for hierarchy
+
+## Animations
+
+Animations should feel **snappy and purposeful** - fast micro-interactions (100-150ms) for buttons and inputs, smooth transitions (250-300ms) for page changes and dialogs, with spring physics for natural movement. Use subtle scale transforms (0.98→1.0) on button press, slide-in animations for modals, and fade effects for state changes. Avoid unnecessary flourishes - every animation serves feedback or orientation.
+
+## Component Selection
+
+- **Components**: 
+  - `Card`, `Button`, `Input`, `Select`, `Checkbox`, `Switch` for core UI
+  - `Dialog`, `Tabs`, `Badge`, `Progress`, `Separator` for layout and feedback
+  - `Heading`, `Text`, `List`, `Grid` for typography and layout primitives
+  - `ScrollArea` for contained scrollable regions
+  - `Tooltip` for contextual help
+  
+- **Customizations**: 
+  - `StatusBadge` - Status indicator with predefined styles
+  - `DataCard` - Stat card with icon, trend, and loading states
+  - `SearchInput` - Input with search icon and clear button
+  - `ActionBar` - Title with action buttons
+  - All new atomic components follow the 150 LOC limit
+  
+- **States**: 
+  - Buttons: subtle scale on press, glow effect on hover, disabled with opacity
+  - Inputs: border color shift on focus, inline validation icons, smooth error states
+  - Cards: subtle lift shadow on hover for interactive cards
