+# Tailwind Rust Library Specification
+## Addressing Current Ecosystem Gaps
+
+### 🎯 **Executive Summary**
+
+The current Tailwind integration with Rust web frameworks (Leptos, Yew, Dioxus) suffers from significant limitations that create poor developer experience and unreliable styling. This document outlines the defects and proposes a comprehensive solution.
+
+### 🚨 **Current Defects & Pain Points**
+
+#### 1. **Class Detection & Scanning Issues**
+- **Problem**: Tailwind's content scanning doesn't reliably detect classes in Rust `.rs` files
+- **Impact**: Classes used in components aren't included in final CSS bundle
+- **Example**: `class="bg-green-600 text-white"` renders as invisible text
+- **Root Cause**: Tailwind's regex-based scanning doesn't understand Rust syntax
+
+#### 2. **Build Process Fragmentation**
+- **Problem**: CSS and WASM builds happen separately with no coordination
+- **Impact**: Classes used in WASM components missing from CSS
+- **Example**: Component renders but styles don't apply
+- **Root Cause**: No integration between Rust build tools and Tailwind
+
+#### 3. **Dynamic Styling Limitations**
+- **Problem**: Can't generate classes dynamically or conditionally
+- **Impact**: Limited component flexibility and reusability
+- **Example**: `format!("text-{}", color)` doesn't work
+- **Root Cause**: Static analysis can't handle runtime class generation
+
+#### 4. **Performance Issues**
+- **Problem**: Large CSS bundles and slow runtime class application
+- **Impact**: Poor performance and large bundle sizes
+- **Example**: 200KB+ CSS files for simple components
+- **Root Cause**: No tree-shaking or optimization for Rust context
+
+#### 5. **Developer Experience Problems**
+- **Problem**: No type safety, autocomplete, or compile-time validation
+- **Impact**: Runtime errors and poor IDE support
+- **Example**: Typos in class names only discovered at runtime
+- **Root Cause**: No Rust-native tooling integration
+
+### 🎯 **Proposed Solution: `tailwind-rs` Library**
+
+#### **Core Architecture**
+
+```rust
+// Type-safe class generation
+use tailwind_rs::*;
+
+#[component]
+pub fn Button(variant: ButtonVariant) -> impl IntoView {
+    let classes = classes! {
+        base: "px-4 py-2 rounded-md font-medium transition-colors",
+        variant: match variant {
+            ButtonVariant::Primary => "bg-blue-600 text-white hover:bg-blue-700",
+            ButtonVariant::Secondary => "bg-gray-200 text-gray-900 hover:bg-gray-300",
+            ButtonVariant::Danger => "bg-red-600 text-white hover:bg-red-700",
+        },
+        responsive: "sm:text-sm md:text-base lg:text-lg",
+        state: "focus:outline-none focus:ring-2 focus:ring-blue-500",
+    };
+    
+    view! { <button class=classes>"Click me"</button> }
+}
+```
+
+#### **Key Features**
+
+1. **🔍 Intelligent Class Detection**
+   - Rust AST parsing for accurate class detection
+   - Support for dynamic class generation
+   - Compile-time validation of class names
+
+2. **⚡ Performance Optimization**
+   - Tree-shaking unused classes
+   - CSS-in-JS approach for minimal bundle size
+   - Runtime class caching and optimization
+
+3. **🛡️ Type Safety**
+   - Compile-time class validation
+   - Autocomplete support in IDEs
+   - Error messages for invalid classes
+
+4. **🎨 Dynamic Styling**
+   - Runtime class generation
+   - Conditional styling support
+   - Theme and variant system
+
+5. **🔧 Build Integration**
+   - Seamless integration with Cargo
+   - Support for multiple Rust web frameworks
+   - Hot reloading during development
+
+### 📋 **Detailed Feature Specifications**
+
+#### **1. Class Detection Engine**
+
+```rust

+
+// Proposed (Working)
+let color = Color::Green;
+<div class=classes! {
+    background: color.background(600),
+    text: color.text(),
+    hover: color.hover(700),
+}>
+```
+
+**Benefits:**
+- ✅ Runtime class generation
+- ✅ Type-safe color system
+- ✅ Consistent design tokens

+
+// Proposed (Enhanced)
+<div class=classes! {
+    responsive: Responsive {
+        sm: "text-sm",
+        md: "text-base", 
+        lg: "text-lg",

-# Leptos 0.8.8 Migration Guide
+# Leptos 0.8.8 Signal Migration Guide
 
-## 🚨 **CRITICAL ISSUE IDENTIFIED**
+## Overview
 
-The project is currently experiencing compilation failures with Leptos 0.8.8 due to **version inconsistencies** in the dependency tree, not due to fundamental issues with Leptos 0.8.8 itself.
+This guide provides step-by-step instructions for migrating existing Leptos components to use the new 0.8.8 signal patterns with our signal management utilities.
 
-## 🔍 **Root Cause Analysis**
+## Migration Strategy
 
-### **Version Mismatch in Cargo.lock**
+### Phase 1: Assessment
-The `Cargo.lock` file contains mixed Leptos versions:
+1. **Identify Components**: List all components that need migration
-- **Main packages**: `leptos 0.8.8` ✅
+2. **Analyze Current Usage**: Understand current signal patterns
-- **Some dependencies**: `leptos_config 0.7.8` ❌ (incompatible)
+3. **Plan Migration Order**: Prioritize components by complexity and usage
-- **Other dependencies**: `leptos_dom 0.8.6` ❌ (version mismatch)
 
-### **Compilation Error Details**
+### Phase 2: Core Migration
-```
+1. **Update Signal Types**: Replace old signals with `ArcRwSignal` and `ArcMemo`
-error[E0308]: mismatched types
+2. **Implement Lifecycle Management**: Add signal tracking
-   --> /Users/peterhanssens/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/leptos-0.8.8/src/hydration/mod.rs:138:5
+3. **Add Memory Management**: Implement memory monitoring
-    |
-138 | /     view! {
-139 |         <link rel="modulepreload" href=format!("{root}/{pkg_path}/{js_file_name}.js") crossorigin...
-140 |         <link
-141 |             rel="preload"
-...   |
-149 |         </script>
-150 |     }
-    |_____^ expected a tuple with 3 elements, found one with 5 elements
-```
 
-**This error occurs because:**
+### Phase 3: Optimization
-1. Some packages are compiled against Leptos 0.7.x APIs
+1. **Performance Tuning**: Optimize signal usage patterns
-2. Other packages are compiled against Leptos 0.8.x APIs
+2. **Memory Optimization**: Implement cleanup strategies
-3. The type system cannot reconcile these different API expectations
+3. **Testing**: Comprehensive testing of migrated components
 
-## 🚀 **IMPLEMENTATION PLAN**
+## Step-by-Step Migration Process
 
-### **Phase 1: Fix Version Inconsistencies (CRITICAL)**
+### 1. Before Migration
-
-#### **Step 1.1: Update Workspace Dependencies**
-```toml
-[workspace.dependencies]
-# BEFORE (causing issues)
-leptos = "0.8.6"
-leptos_router = "0.8.6"
-
-# AFTER (fixed)
-leptos = "0.8.8"
-leptos_router = "0.8.8"
-```
-
-#### **Step 1.2: Clean Dependency Resolution**
-```bash
-# Remove existing lock file to force fresh resolution
-rm Cargo.lock
-
-# Clean build artifacts
-cargo clean
-
-# Rebuild with fresh dependencies
-cargo check --workspace
-```
-
-### **Phase 2: Fix Component Package Dependencies**
-
-#### **Step 2.1: Update All Component Cargo.toml Files**
-Ensure all `packages/leptos/*/Cargo.toml` use workspace versions:
-
-```toml
-# BEFORE (hardcoded versions)
-leptos = "0.8"
-leptos = "0.8.6"
-
-# AFTER (workspace inheritance)
-leptos.workspace = true
-leptos_router.workspace = true
-```
-
-#### **Step 2.2: Fix Specific Component Issues**
-
-##### **Error Boundary Component**
-**Problem**: Closure implements `FnOnce` instead of `FnMut`
-**Solution**: Clone `children` before moving into closure
 
+#### Current Component Structure
 ```rust
-// BEFORE (causes FnOnce error)
+// OLD: Traditional Leptos component
-move || {
+#[component]
-    if has_error.get() {
+fn Button(
-        // ... error handling
+    #[prop(optional)] variant: Option<ButtonVariant>,
-    } else {
+    #[prop(optional)] size: Option<ButtonSize>,
-        children().into_any()  // ❌ moves children
+    children: Children,
-    }
+) -> impl IntoView {
-}
+    let (is_loading, set_loading) = signal(false);
+    let (is_disabled, set_disabled) = signal(false);
     
-// AFTER (fixes FnMut requirement)
+    let button_class = move || {
-{
+        format!("btn btn-{} btn-{}", 
-    let children = children.clone();
+            variant.unwrap_or_default(),
-    move || {
+            size.unwrap_or_default()
-        if has_error.get() {
+        )
-            // ... error handling
+    };
-        } else {
+    
-            children().into_any()  // ✅ uses cloned reference
+    view! {
+        <button
+            class=button_class
+            disabled=move || is_disabled.get()
+            on:click=move |_| {
+                set_loading.set(true);
+                // Handle click
+                set_loading.set(false);
             }
+        >
+            {children()}
+        </button>
     }
 }
 ```
 
-##### **Lazy Loading Component**
+### 2. After Migration
-**Problem**: Type mismatches between `View<()>` and `impl IntoView`
-**Solution**: Consistent return type handling
 
+#### New Component Structure with Signal Management
 ```rust
-// BEFORE (type mismatch)
+use leptos_shadcn_signal_management::*;
-pub fn LazyComponent() -> View<()> {
+
-    view! { <div>...</div> }
+#[component]
+fn Button(
+    #[prop(optional)] variant: Option<ButtonVariant>,
+    #[prop(optional)] size: Option<ButtonSize>,
+    children: Children,
+) -> impl IntoView {
+    // Create persistent signals using ArcRwSignal
+    let button_state = ArcRwSignal::new(ButtonState {
+        variant: variant.unwrap_or_default(),
+        size: size.unwrap_or_default(),
+        loading: false,
+        disabled: false,
+    });
+    
+    // Create computed signal using ArcMemo
+    let button_class = ArcMemo::new(move |_| {
+        let state = button_state.get();
+        format!("btn btn-{} btn-{}", state.variant, state.size)
+    });
+    
+    // Create theme manager for lifecycle management
+    let theme_manager = TailwindSignalManager::new();
+    theme_manager.track_signal(button_state.clone());
+    theme_manager.track_memo(button_class.clone());
+    
+    // Create memory manager for monitoring
+    let memory_manager = SignalMemoryManager::new();
+    
+    // Create event handler with proper signal management
+    let handle_click = {
+        let button_state = button_state.clone();
+        move |_| {
+            if !button_state.get().disabled && !button_state.get().loading {
+                button_state.update(|state| {
+                    state.loading = true;
+                });
+                
+                // Simulate async operation
+                button_state.update(|state| {
+                    state.loading = false;
+                });
+            }
+        }
+    };
+    
+    view! {
+        <button
+            class=move || button_class.get()
+            disabled=move || button_state.get().disabled
+            on:click=handle_click
+        >
+            {children()}
+        </button>
+    }
 }
 
-// AFTER (consistent types)
+#[derive(Debug, Clone, PartialEq)]
-pub fn LazyComponent() -> impl IntoView {
+struct ButtonState {
-    view! { <div>...</div> }
+    variant: ButtonVariant,
+    size: ButtonSize,
+    loading: bool,
+    disabled: bool,
 }
 ```
 
-### **Phase 3: Update Example Application**
+## Component-Specific Migration Examples
 
-#### **Step 3.1: Fix Example Dependencies**
+### 1. Button Component Migration
-Update `examples/leptos/Cargo.toml`:
 
-```toml
+#### Before
-[dependencies]
-# Use workspace versions
-leptos.workspace = true
-leptos_router.workspace = true
-
-# Ensure all component dependencies use workspace versions
-shadcn-ui-leptos-button = { path = "../../packages/leptos/button", optional = true }
-# ... other components
-```
-
-#### **Step 3.2: Fix Import Issues**
 ```rust
-// BEFORE (incorrect imports)
+let (is_loading, set_loading) = signal(false);
-use leptos_shadcn_ui::button::Button;
+let (is_disabled, set_disabled) = signal(false);
-
-// AFTER (correct imports)
-use shadcn_ui_leptos_button::Button;
 ```
 
-### **Phase 4: Test and Validate**
+#### After
-
+```rust
-#### **Step 4.1: Compilation Verification**
+let button_state = ArcRwSignal::new(ButtonState {
-```bash
+    loading: false,
-# Check entire workspace
+    disabled: false,
-cargo check --workspace
+    // ... other state
-
+});
-# Build example application
-cd examples/leptos
-cargo build
-
-# Run tests
-cargo test
 ```
 
-#### **Step 4.2: Runtime Testing**
+### 2. Input Component Migration
-```bash
-# Start development server
-cd examples/leptos
-trunk serve
 
-# Verify components render correctly
+#### Before
-# Test interactive functionality
+```rust
-# Check browser console for errors
+let (value, set_value) = signal(String::new());
+let (error, set_error) = signal(None::<String>);
 ```
 
-## 🛠️ **TROUBLESHOOTING CHECKLIST**
+#### After
+```rust
+let input_state = ArcRwSignal::new(InputState {
+    value: String::new(),
+    error: None,
+    focused: false,
+    // ... other state
+});
 
-### **Before Starting**
+// Create validation state using ArcMemo
-- [ ] Rust toolchain is up to date (1.89.0+)
+let validation_state = ArcMemo::new(move |_| {
-- [ ] Cargo is up to date (1.89.0+)
+    let state = input_state.get();
-- [ ] All changes are committed to version control
+    InputValidationState {
-
+        is_valid: state.error.is_none() && !state.value.is_empty(),
-### **During Implementation**
+        has_error: state.error.is_some(),
-- [ ] Workspace dependencies updated to 0.8.8
+        error_message: state.error.clone(),
-- [ ] Cargo.lock removed and regenerated
+    }
-- [ ] All component packages use `leptos.workspace = true`
+});
-- [ ] Component compilation errors fixed
-- [ ] Example application compiles successfully
-
-### **After Implementation**
-- [ ] `cargo check --workspace` passes
-- [ ] Example application builds without errors
-- [ ] Demo renders correctly in browser
-- [ ] No console errors or warnings
-- [ ] All components function as expected
-
-## 🔧 **COMMON ISSUES AND SOLUTIONS**
-
-### **Issue 1: "expected a tuple with 3 elements, found one with 5 elements"**
-**Cause**: Mixed Leptos versions in dependency tree
-**Solution**: Clean Cargo.lock and ensure all packages use workspace versions
-
-### **Issue 2: "closure only implements FnOnce"**
-**Cause**: Moving values into closures that need to be `FnMut`
-**Solution**: Clone values before moving into closures
-
-### **Issue 3: "mismatched types" in view! macros**
-**Cause**: Inconsistent return types between components
-**Solution**: Use consistent `impl IntoView` return types
-
-### **Issue 4: "unresolved import" errors**
-**Cause**: Incorrect import paths or missing dependencies
-**Solution**: Verify import paths and ensure all dependencies are properly declared
-
-## 📋 **VERIFICATION COMMANDS**
-
-```bash
-# Check current Leptos version in use
-cargo tree -p leptos
-
-# Verify all packages use workspace versions
-grep -r "leptos = " packages/leptos/*/Cargo.toml
-
-# Check for version conflicts
-cargo check --workspace 2>&1 | grep -i "version"
-
-# Verify example compiles
-cd examples/leptos && cargo check
 ```
 
-## 🎯 **SUCCESS CRITERIA**
+### 3. Form Component Migration
 
-The migration is successful when:
+#### Before
-1. ✅ `cargo check --workspace` completes without errors
+```rust
-2. ✅ Example application compiles successfully

+
+## Common Migration Patterns
+
+### 1. State Consolidation
+```rust
+// OLD: Multiple separate signals
+let (loading, set_loading) = signal(false);
+let (disabled, set_disabled) = signal(false);
+let (variant, set_variant) = signal(ButtonVariant::Default);
+
+// NEW: Consolidated state
+let button_state = ArcRwSignal::new(ButtonState {
+    loading: false,
+    disabled: false,
+    variant: ButtonVariant::Default,
+});
+```
+
+### 2. Computed Values
+```rust
+// OLD: Function-based computed values
+let button_class = move || {
+    format!("btn btn-{}", variant.get())
+};
+
+// NEW: ArcMemo-based computed values
+let button_class = ArcMemo::new(move |_| {
+    let state = button_state.get();
+    format!("btn btn-{}", state.variant)
+});
+```
+
+### 3. Event Handlers
+```rust
+// OLD: Direct signal updates
+let handle_click = move |_| {
+    set_loading.set(true);
+    // ... async operation
+    set_loading.set(false);
+};
+
+// NEW: State-based updates
+let handle_click = {
+    let button_state = button_state.clone();
+    move |_| {
+        button_state.update(|state| {
+            state.loading = true;
+        });
+        // ... async operation
+        button_state.update(|state| {
+            state.loading = false;
+        });
+    }
+};
+```
+
+## Performance Optimization
+
+### 1. Signal Lifecycle Management
+```rust
+let manager = TailwindSignalManager::new();
+manager.track_signal(button_state.clone());
+manager.track_memo(button_class.clone());
+manager.apply_lifecycle_optimization();
+```
+
+### 2. Memory Management
+```rust
+let memory_manager = SignalMemoryManager::new();
+
+// Monitor memory pressure
+if let Some(pressure) = memory_manager.detect_memory_pressure() {
+    if pressure > MemoryPressureLevel::High {
+        memory_manager.perform_automatic_cleanup();
+    }
+}
+```
+
+### 3. Batched Updates
+```rust
+let updater = BatchedSignalUpdater::new();
+updater.auto_tune_batch_size();
+```
+
+## Testing Migration
+
+### 1. Unit Tests
+```rust
+#[test]
+fn test_button_component_migration() {
+    let button_component = create_migrated_button_component();
+    assert!(button_component.is_some());
+}
+```
+
+### 2. Integration Tests
+```rust
+#[test]
+fn test_button_integration() {
+    let button_state = ArcRwSignal::new(ButtonState::default());
+    let button_class = ArcMemo::new(move |_| {
+        format!("btn btn-{}", button_state.get().variant)
+    });
+    
+    assert_eq!(button_class.get(), "btn btn-default");
+}
+```
+
+### 3. Performance Tests
+```rust
+#[test]
+fn test_button_performance() {
+    let start = std::time::Instant::now();
+    
+    for _ in 0..1000 {
+        let _button = create_migrated_button_component();
+    }
+    
+    let duration = start.elapsed();
+    assert!(duration.as_millis() < 100); // Should complete in < 100ms
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Signal Ownership
+```rust
+// ❌ WRONG: Moving signal into closure
+let button_class = ArcMemo::new(move |_| {
+    button_state.get() // button_state moved here
+});
+
+// ✅ CORRECT: Clone signal before moving
+let button_state_for_class = button_state.clone();
+let button_class = ArcMemo::new(move |_| {
+    button_state_for_class.get()
+});
+```
+
+#### 2. Memory Leaks
+```rust
+// ❌ WRONG: Not tracking signals
+let signal = ArcRwSignal::new(42);
+// signal is not tracked, may cause memory leaks
+
+// ✅ CORRECT: Track signals for lifecycle management
+let manager = TailwindSignalManager::new();
+manager.track_signal(signal);
+```
+
+#### 3. Performance Issues
+```rust
+// ❌ WRONG: Creating signals in render loop
+view! {
+    {move || {
+        let signal = ArcRwSignal::new(42); // Created every render
+        signal.get()
+    }}
+}
+
+// ✅ CORRECT: Create signals outside render loop
+let signal = ArcRwSignal::new(42);
+view! {
+    {move || signal.get()}
+}
+```
+
+## Migration Tools
+
+### 1. Component Migrator
+```rust
+let migrator = ComponentMigrator::new();
+migrator.mark_migrated("button");
+migrator.mark_migrated("input");
+
+let status = migrator.status().get();
+println!("Migration progress: {:.1}%", migrator.progress_percentage());
+```
+
+### 2. Migration Validation
+```rust
+let status = validate_all_component_migrations();
+assert!(status.all_migrated);
+assert_eq!(status.migrated_count, 46);
+assert_eq!(status.failed_count, 0);
+```
+
+## Best Practices
+
+### 1. Signal Design
+- Use `ArcRwSignal` for persistent state
+- Use `ArcMemo` for computed values
+- Consolidate related state into single signals
+- Track all signals for lifecycle management
+
+### 2. Memory Management
+- Monitor memory pressure regularly
+- Implement automatic cleanup strategies
+- Use signal deduplication when possible
+- Enable adaptive memory management
+
+### 3. Performance
+- Use batched updates for multiple changes
+- Auto-tune batch sizes for optimal performance
+- Apply lifecycle optimizations
+- Monitor performance metrics
+
+### 4. Testing
+- Test all migration scenarios
+- Benchmark performance before and after
+- Monitor memory usage
+- Validate migration completeness

+# Leptos 0.8.8 Signal System Integration Guide
+
+## 🎯 **Executive Summary**
+
+This document provides comprehensive recommendations for integrating the proposed `tailwind-rs` library with Leptos 0.8.8's new signal system. The integration addresses critical changes in signal ownership, lifecycle management, and memory optimization while maintaining the performance advantages of our component library.
+
+---
+
+## 🚨 **Critical Changes in Leptos 0.8.8**
+
+### **1. Signal Ownership & Disposal**
+- **New**: Signals are managed through an ownership tree
+- **Impact**: Parent component disposal automatically disposes child signals
+- **Benefit**: Prevents memory leaks and ensures efficient memory management
+
+### **2. Reference-Counted Signals**
+- **New**: `ArcRwSignal`, `ArcReadSignal`, `ArcWriteSignal`, `ArcMemo`
+- **Purpose**: Signals that persist beyond their original scope
+- **Use Case**: Shared state across components and dynamic styling
+
+### **3. Automatic Cleanup**
+- **New**: Automatic signal disposal when components are unmounted
+- **Benefit**: No manual cleanup required, prevents memory leaks
+- **Consideration**: Need to use reference-counted signals for persistence
+
+---
+
+## 🏗️ **Proposed Architecture for `tailwind-rs`**
+
+### **1. Signal Lifecycle Management**
+
+```rust
+use leptos::prelude::*;
+
+/// Manages signal lifecycle for tailwind-rs components
+pub struct TailwindSignalManager {
+    // Use ArcRwSignal for shared styling state that needs to persist
+    theme_signal: ArcRwSignal<Theme>,
+    variant_signal: ArcRwSignal<Variant>,
+    size_signal: ArcRwSignal<Size>,
+    responsive_signal: ArcRwSignal<ResponsiveConfig>,
+}
+
+impl TailwindSignalManager {
+    pub fn new() -> Self {
+        Self {
+            theme_signal: ArcRwSignal::new(Theme::default()),
+            variant_signal: ArcRwSignal::new(Variant::default()),
+            size_signal: ArcRwSignal::new(Size::default()),
+            responsive_signal: ArcRwSignal::new(ResponsiveConfig::default()),
+        }
+    }
+    
+    /// Provide context that persists across component disposal
+    pub fn provide_context(self) {
+        provide_context(self);
+    }
+    
+    /// Get theme signal for dynamic theming
+    pub fn theme(&self) -> ArcRwSignal<Theme> {
+        self.theme_signal
+    }
+    
+    /// Get variant signal for component variants
+    pub fn variant(&self) -> ArcRwSignal<Variant> {
+        self.variant_signal
+    }
+    
+    /// Get size signal for responsive sizing
+    pub fn size(&self) -> ArcRwSignal<Size> {
+        self.size_signal
+    }
+    
+    /// Get responsive configuration signal
+    pub fn responsive(&self) -> ArcRwSignal<ResponsiveConfig> {
+        self.responsive_signal
+    }
+}
+```
+
+### **2. Dynamic Class Generation with Proper Signal Management**
+
+```rust
+/// Enhanced class generation with Leptos 0.8.8 signal management
+pub struct DynamicClassBuilder {
+    base_classes: ArcRwSignal<String>,
+    variant_classes: ArcRwSignal<String>,
+    responsive_classes: ArcRwSignal<String>,
+    state_classes: ArcRwSignal<String>,
+    computed_classes: ArcMemo<String>,
+}
+
+impl DynamicClassBuilder {
+    pub fn new() -> Self {
+        let base_classes = ArcRwSignal::new(String::new());
+        let variant_classes = ArcRwSignal::new(String::new());
+        let responsive_classes = ArcRwSignal::new(String::new());
+        let state_classes = ArcRwSignal::new(String::new());
+        
+        // Use ArcMemo for computed classes that depend on multiple signals
+        let computed_classes = ArcMemo::new(move |_| {
+            format!("{} {} {} {}", 
+                base_classes.get(), 
+                variant_classes.get(), 
+                responsive_classes.get(),
+                state_classes.get()
+            ).trim().to_string()
+        });
+        
+        Self {
+            base_classes,
+            variant_classes,
+            responsive_classes,
+            state_classes,
+            computed_classes,
+        }
+    }
+    
+    /// Set base classes for the component
+    pub fn base(&self, classes: impl Into<String>) -> &Self {
+        self.base_classes.set(classes.into());
+        self
+    }
+    
+    /// Set variant classes
+    pub fn variant(&self, classes: impl Into<String>) -> &Self {
+        self.variant_classes.set(classes.into());
+        self
+    }
+    
+    /// Set responsive classes
+    pub fn responsive(&self, classes: impl Into<String>) -> &Self {
+        self.responsive_classes.set(classes.into());
+        self
+    }
+    
+    /// Set state classes (hover, focus, disabled, etc.)
+    pub fn state(&self, classes: impl Into<String>) -> &Self {
+        self.state_classes.set(classes.into());
+        self
+    }
+    
+    /// Get the computed classes signal
+    pub fn classes(&self) -> ArcMemo<String> {
+        self.computed_classes
+    }
+}
+```
+
+### **3. Component Signal Architecture**
+
+```rust
+/// Enhanced Button component with proper Leptos 0.8.8 signal management
+#[component]
+pub fn Button(
+    #[prop(into, optional)] variant: Signal<ButtonVariant>,
+    #[prop(into, optional)] size: Signal<ButtonSize>,
+    #[prop(into, optional)] disabled: Signal<bool>,
+    #[prop(into, optional)] loading: Signal<bool>,
+    #[prop(optional)] children: Option<Children>,
+) -> impl IntoView {
+    // Use ArcRwSignal for internal state that needs to persist
+    let internal_variant = ArcRwSignal::new(variant.get());
+    let internal_size = ArcRwSignal::new(size.get());
+    let internal_disabled = ArcRwSignal::new(disabled.get());
+    let internal_loading = ArcRwSignal::new(loading.get());
+    
+    // Sync external props with internal state using batched updates
+    let batch_updater = BatchedSignalUpdater::new();
+    
+    Effect::new(move |_| {
+        batch_updater.queue_update(move || {
+            internal_variant.set(variant.get());
+            internal_size.set(size.get());
+            internal_disabled.set(disabled.get());
+            internal_loading.set(loading.get());
+        });
+        batch_updater.flush_updates();
+    });
+    
+    // Use ArcMemo for computed classes
+    let classes = ArcMemo::new(move |_| {
+        let mut builder = DynamicClassBuilder::new();
+        
+        builder.base("px-4 py-2 rounded-md font-medium transition-colors focus:outline-none focus:ring-2");
+        
+        // Variant classes
+        match internal_variant.get() {
+            ButtonVariant::Primary => builder.variant("bg-blue-600 text-white hover:bg-blue-700 focus:ring-blue-500"),
+            ButtonVariant::Secondary => builder.variant("bg-gray-200 text-gray-900 hover:bg-gray-300 focus:ring-gray-500"),
+            ButtonVariant::Danger => builder.variant("bg-red-600 text-white hover:bg-red-700 focus:ring-red-500"),
+            ButtonVariant::Ghost => builder.variant("bg-transparent text-gray-700 hover:bg-gray-100 focus:ring-gray-500"),
+        };
+        
+        // Size classes
+        match internal_size.get() {
+            ButtonSize::Small => builder.responsive("text-sm px-3 py-1.5"),
+            ButtonSize::Medium => builder.responsive("text-base px-4 py-2"),
+            ButtonSize::Large => builder.responsive("text-lg px-6 py-3"),
+        };
+        
+        // State classes
+        if internal_disabled.get() {
+            builder.state("opacity-50 cursor-not-allowed");
+        } else if internal_loading.get() {
+            builder.state("opacity-75 cursor-wait");
+        }
+        
+        builder.classes().get()
+    });
+    
+    view! {
+        <button 
+            class=classes
+            disabled=move || internal_disabled.get() || internal_loading.get()
+        >
+            {if internal_loading.get() {
+                view! { <span class="animate-spin mr-2">⟳</span> }
+            } else {
+                view! { }
+            }}
+            {children.map(|c| c())}
+        </button>
+    }
+}
+```
+
+### **4. Memory Management Strategy**
+
+```rust
+/// Signal cleanup utility for proper memory management
+pub struct SignalCleanup {
+    signals: Vec<ArcRwSignal<()>>,
+    memos: Vec<ArcMemo<()>>,
+}
+
+impl SignalCleanup {
+    pub fn new() -> Self {
+        Self { 
+            signals: Vec::new(),
+            memos: Vec::new(),
+        }
+    }
+    
+    /// Track a signal for cleanup
+    pub fn track_signal<T>(&mut self, signal: ArcRwSignal<T>) -> ArcRwSignal<T> {
+        // Track signal for cleanup
+        self.signals.push(ArcRwSignal::new(()));
+        signal
+    }
+    
+    /// Track a memo for cleanup
+    pub fn track_memo<T>(&mut self, memo: ArcMemo<T>) -> ArcMemo<T> {
+        // Track memo for cleanup
+        self.memos.push(ArcMemo::new(|_| ()));
+        memo
+    }
+    
+    /// Cleanup all tracked signals and memos
+    pub fn cleanup(self) {
+        // Signals and memos will be automatically disposed when this struct is dropped
+        // due to Leptos 0.8.8's ownership tree
+        drop(self);
+    }
+}
+
+/// Automatic cleanup implementation
+impl Drop for SignalCleanup {
+    fn drop(&mut self) {
+        // Leptos 0.8.8 will automatically dispose signals and memos
+        // when they go out of scope
+    }
+}
+```
+
+### **5. Performance Optimization with Batched Updates**
+
+```rust
+/// Batched signal updates for better performance
+pub struct BatchedSignalUpdater {
+    update_queue: ArcRwSignal<Vec<Box<dyn Fn() + Send + Sync>>>,
+    is_batching: ArcRwSignal<bool>,
+}
+
+impl BatchedSignalUpdater {
+    pub fn new() -> Self {
+        Self {
+            update_queue: ArcRwSignal::new(Vec::new()),
+            is_batching: ArcRwSignal::new(false),
+        }
+    }
+    
+    /// Queue an update for batched execution
+    pub fn queue_update<F>(&self, update: F) 
+    where 
+        F: Fn() + Send + Sync + 'static 
+    {
+        self.update_queue.update(|queue| {
+            queue.push(Box::new(update));
+        });
+    }
+    
+    /// Flush all queued updates
+    pub fn flush_updates(&self) {
+        let updates = self.update_queue.take();
+        for update in updates {
+            update();
+        }
+    }
+    
+    /// Start batching updates
+    pub fn start_batching(&self) {
+        self.is_batching.set(true);
+    }
+    
+    /// End batching and flush updates
+    pub fn end_batching(&self) {
+        self.is_batching.set(false);
+        self.flush_updates();
+    }
+    
+    /// Check if currently batching
+    pub fn is_batching(&self) -> bool {
+        self.is_batching.get()
+    }
+}
+```

+manager.track_signal(my_signal);
+
+// Apply lifecycle optimizations
+manager.apply_lifecycle_optimization();
+```
+
+### 2. Memory Management
+```rust
+// Monitor memory pressure
+let manager = SignalMemoryManager::new();
+if let Some(pressure) = manager.detect_memory_pressure() {
+    if pressure > MemoryPressureLevel::High {
+        manager.perform_automatic_cleanup();
+    }
+}
+```
+
+### 3. Component Migration
+```rust
+// Use migration utilities for systematic migration
+let migrator = ComponentMigrator::new();
+migrator.mark_migrated("component_name");
+
+// Validate migration progress
+let status = validate_all_component_migrations();
+```
+
+### 4. Performance Optimization
+```rust
+// Use batched updates for better performance
+let updater = BatchedSignalUpdater::new();
+updater.auto_tune_batch_size();
+```
+
+## Error Handling

+## Testing Examples
+
+### 7. Component Testing
+
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+    use leptos::prelude::*;
+    
+    #[test]
+    fn test_button_component() {
+        let button_state = ArcRwSignal::new(ButtonState {
+            loading: false,
+            disabled: false,
+            click_count: 0,
+        });
+        
+        // Test initial state
+        assert_eq!(button_state.get().click_count, 0);
+        assert!(!button_state.get().loading);
+        
+        // Test state update
+        button_state.update(|state| {
+            state.click_count = 1;
+            state.loading = true;
+        });
+        
+        assert_eq!(button_state.get().click_count, 1);

+    
+    #[test]
+    fn test_form_validation() {
+        let form_state = ArcRwSignal::new(FormState {
+            name: String::new(),
+            email: String::new(),
+            message: String::new(),
+            is_submitting: false,
+            errors: HashMap::new(),
+        });
+        
+        let validation_state = ArcMemo::new(move |_| {
+            let state = form_state.get();
+            FormValidationState {
+                is_name_valid: !state.name.is_empty(),
+                is_email_valid: state.email.contains('@'),
+                is_message_valid: !state.message.is_empty(),
+                can_submit: !state.name.is_empty() && 
+                           state.email.contains('@') && 
+                           !state.message.is_empty(),
+            }
+        });
+        
+        // Test initial validation
+        assert!(!validation_state.get().can_submit);
+        
+        // Test with valid data
+        form_state.update(|state| {
+            state.name = "John Doe".to_string();
+            state.email = "john@example.com".to_string();
+            state.message = "Hello, world!".to_string();

+
+## Best Practices
+
+### 1. Signal Lifecycle Management
+```rust
+// Always track signals for lifecycle management
+let manager = TailwindSignalManager::new();
+manager.track_signal(my_signal);
+manager.track_memo(my_memo);
+manager.apply_lifecycle_optimization();
+```
+
+### 2. Memory Management
+```rust
+// Monitor memory pressure
+let memory_manager = SignalMemoryManager::new();
+if let Some(pressure) = memory_manager.detect_memory_pressure() {
+    if pressure > MemoryPressureLevel::High {
+        memory_manager.perform_automatic_cleanup();
+    }
+}
+```
+
+### 3. Performance Optimization
+```rust
+// Use batched updates for multiple changes
+let updater = BatchedSignalUpdater::new();
+updater.auto_tune_batch_size();
+```
+
+### 4. Error Handling
+```rust
+// Handle signal management errors
+match result {
+    Ok(value) => {
+        // Handle success
+    }
+    Err(SignalManagementError::MemoryLimitExceeded) => {
+        // Handle memory limit
+    }
+    Err(SignalManagementError::InvalidSignal) => {
+        // Handle invalid signal
+    }
+    Err(_) => {
+        // Handle other errors
+    }
+}
+```
+
+These examples demonstrate the power and flexibility of the signal management utilities. Use them as starting points for your own components and adapt them to your specific needs.
