+### **Dash Application Pattern**
+```python
+# src/frontend/main.py
+import dash
+from dash import html, dcc, Input, Output, State, callback
+import dash_mantine_components as dmc
+
+app = dash.Dash(__name__, external_stylesheets=[])
+
+# Layout structure
+app.layout = dmc.MantineProvider(
+    theme={"colorScheme": "light"},
+    children=[
+        dcc.Location(id="url", refresh=False),
+        dmc.Container(
+            children=[
+                html.Div(id="page-content")
+            ],
+            size="xl"
+        )
+    ]
+)
+
+if __name__ == "__main__":
+    app.run_server(host="0.0.0.0", port=8501, debug=True)
+```
+
+### **API Client Pattern**
+```python
+# src/frontend/api_client/client.py
+import httpx
+from typing import Dict, Any, Optional
+
+class JobForgeAPIClient:
+    def __init__(self, base_url: str = "http://backend:8000"):
+        self.base_url = base_url
+        self.token = None
+    
+    async def authenticate(self, email: str, password: str) -> Dict[str, Any]:
+        async with httpx.AsyncClient() as client:
+            response = await client.post(
+                f"{self.base_url}/api/v1/auth/login",
+                json={"email": email, "password": password}
+            )
+            if response.status_code == 200:
+                data = response.json()
+                self.token = data["access_token"]
+                return data
+            else:
+                raise Exception(f"Authentication failed: {response.text}")
+    
+    def get_headers(self) -> Dict[str, str]:
+        if not self.token:
+            raise Exception("Not authenticated")
+        return {"Authorization": f"Bearer {self.token}"}
+```
+
+## Implementation Priorities
+
+### **Phase 1: Authentication UI** (Day 4)
+1. **Login/Register Page**
+   ```python
+   # Login form with Mantine components
+   dmc.Paper([
+       dmc.TextInput(label="Email", id="email-input"),
+       dmc.PasswordInput(label="Password", id="password-input"),
+       dmc.Button("Login", id="login-button"),
+       dmc.Text("Don't have an account?"),
+       dmc.Button("Register", variant="subtle", id="register-button")
+   ])
+   ```
+
+2. **Authentication State Management**
+   - Store JWT token in browser session
+   - Handle authentication status across page navigation
+   - Redirect unauthenticated users to login
+
+### **Phase 2: Application Management UI** (Day 6)
+1. **Application List Sidebar**
+   ```python
+   # Sidebar with application list
+   dmc.Navbar([
+       dmc.Button("New Application", id="new-app-button"),
+       dmc.Stack([
+           dmc.Card([
+               dmc.Text(app.company_name, weight=500),
+               dmc.Text(app.role_title, size="sm"),
+               dmc.Badge(app.status, color="blue")
+           ]) for app in applications
+       ])
+   ])
+   ```
+
+2. **Application Form**
+   ```python
+   # Application creation/editing form
+   dmc.Stack([
+       dmc.TextInput(label="Company Name", id="company-input", required=True),
+       dmc.TextInput(label="Role Title", id="role-input", required=True),
+       dmc.Textarea(label="Job Description", id="job-desc-input", 
+                   minRows=6, required=True),
+       dmc.TextInput(label="Job URL (optional)", id="job-url-input"),
+       dmc.Select(label="Priority", data=["low", "medium", "high"], 
+                 id="priority-select"),
+       dmc.Button("Save Application", id="save-app-button")
+   ])
+   ```
+
+### **Phase 3: Document Management UI** (Day 10)
+1. **Phase Navigation Tabs**
+   ```python
+   # 3-phase workflow tabs
+   dmc.Tabs([
+       dmc.TabsList([
+           dmc.Tab("Research", value="research", 
+                  icon=DashIconify(icon="material-symbols:search")),
+           dmc.Tab("Resume", value="resume",
+                  icon=DashIconify(icon="material-symbols:description")),
+           dmc.Tab("Cover Letter", value="cover-letter",
+                  icon=DashIconify(icon="material-symbols:mail"))
+       ]),
+       dmc.TabsPanel(value="research", children=[...]),
+       dmc.TabsPanel(value="resume", children=[...]),
+       dmc.TabsPanel(value="cover-letter", children=[...])
+   ])
+   ```
+
+2. **Document Editor Component**
+   ```python
+   # Markdown editor with preview
+   dmc.Grid([
+       dmc.Col([
+           dmc.Textarea(
+               label="Edit Document",
+               id="document-editor",
+               minRows=20,
+               autosize=True
+           ),
+           dmc.Group([
+               dmc.Button("Save", id="save-doc-button"),
+               dmc.Button("Cancel", variant="outline", id="cancel-doc-button")
+           ])
+       ], span=6),
+       dmc.Col([
+           dmc.Paper([
+               html.Div(id="document-preview")
+           ], p="md")
+       ], span=6)
+   ])
+   ```
+
+### **Phase 4: AI Processing UI** (Days 7, 9, 11)
+1. **Processing Status Indicators**
+   ```python
+   # AI processing status component
+   def create_processing_status(phase: str, status: str):
+       if status == "pending":
+           return dmc.Group([
+               dmc.Loader(size="sm"),
+               dmc.Text(f"{phase} in progress...")
+           ])
+       elif status == "completed":
+           return dmc.Group([
+               DashIconify(icon="material-symbols:check-circle", color="green"),
+               dmc.Text(f"{phase} completed")
+           ])
+       else:
+           return dmc.Group([
+               DashIconify(icon="material-symbols:play-circle"),
+               dmc.Button(f"Start {phase}", id=f"start-{phase}-button")
+           ])
+   ```
+
+2. **Real-time Status Updates**
+   ```python
+   # Callback for polling processing status
+   @callback(
+       Output("processing-status", "children"),
+       Input("status-interval", "n_intervals"),
+       State("application-id", "data")
+   )
+   def update_processing_status(n_intervals, app_id):
+       if not app_id:
+           return dash.no_update
+       
+       # Poll backend for status
+       status = api_client.get_processing_status(app_id)
+       return create_status_display(status)
+   ```
+
+## User Experience Patterns
+
+### **Navigation Flow**
+1. **Login/Register** → **Dashboard** → **Select/Create Application** → **3-Phase Workflow**
+2. **Sidebar Navigation**: Always visible list of user's applications
+3. **Phase Tabs**: Clear indication of current phase and completion status
+4. **Document Editing**: Seamless transition between viewing and editing
+
+### **Loading States**
+- Show loading spinners during API calls
+- Disable buttons during processing to prevent double-clicks
+- Display progress indicators for AI processing phases
+- Provide clear feedback when operations complete
+
+### **Error Handling**
+```python
+# Error notification pattern
+def show_error_notification(message: str):
+    return dmc.Notification(
+        title="Error",
+        id="error-notification",
+        action="show",
+        message=message,
+        color="red",
+        icon=DashIconify(icon="material-symbols:error")
+    )
+```
+
+## Quality Standards
+
+### **UI/UX Requirements**
+- **Responsive Design**: Works on desktop, tablet, and mobile
+- **Loading States**: Clear feedback during all async operations
+- **Error Handling**: Friendly error messages with actionable guidance
+- **Accessibility**: Proper labels, keyboard navigation, screen reader support
+- **Performance**: Components render in <100ms, smooth interactions
+
+### **Code Quality**
+- **Component Reusability**: Create modular, reusable components
+- **State Management**: Clean separation of UI state and data
+- **API Integration**: Proper error handling and loading states
+- **Type Safety**: Use proper type hints where applicable
+
+## Development Workflow
+
+### **Daily Development Pattern**
+1. **Morning**: Review UI requirements and design specifications
+2. **Implementation**: Build components following Mantine design patterns
+3. **Testing**: Test user interactions and API integration
+4. **Refinement**: Polish UI and improve user experience
+
+### **Testing Strategy**
+```bash
+# Manual testing workflow
+1. Start frontend: docker-compose up frontend
+2. Test user flows: registration → login → application creation → AI processing
+3. Verify responsive design across different screen sizes
+4. Check error handling with network interruptions
+```
+
+### **Validation Commands**
+```bash
+# Frontend health check
+curl http://localhost:8501
+
+# Check logs for errors
+docker-compose logs frontend
+```
+
+## Key Context Files
+
+**Always reference these files:**
+- `docs/api_specification.md` - Backend API endpoints and data models
+- `requirements-frontend.txt` - All required Python dependencies
+- `GETTING_STARTED.md` - Day-by-day implementation guide with UI priorities
+- `MVP_CHECKLIST.md` - Track frontend component completion
+
+## Success Criteria
+
+Your frontend implementation is successful when:
+- [ ] Users can register, login, and maintain session state
+- [ ] Application management (create, edit, list) works intuitively
+- [ ] 3-phase AI workflow is clearly represented and navigable
+- [ ] Document editing provides smooth, responsive experience
+- [ ] Real-time status updates show AI processing progress
+- [ ] Error states provide helpful feedback to users
+- [ ] UI is professional, modern, and responsive across devices
+
+**Current Priority**: Start with authentication UI (login/register forms) and session state management, then build application management interface.
