## User Stories

### US-1: View Dashboard Overview
**As a** user  
**I want to** see an overview of my key metrics  
**So that** I can quickly understand my account status

**Acceptance Criteria:**
- WHEN I navigate to `/dashboard` THEN I see 4 metric cards (total tasks, completed, in progress, pending)
- WHEN metrics load THEN I see loading skeletons
- WHEN metrics fail to load THEN I see error message with retry button
- WHEN I view on mobile THEN cards stack vertically

### US-2: View Task Completion Chart
**As a** user  
**I want to** see a chart of my task completion over time  
**So that** I can track my productivity

**Acceptance Criteria:**
- WHEN I view dashboard THEN I see a line chart showing last 7 days of task completions
- WHEN I hover over data points THEN I see exact values in tooltip
- WHEN chart loads THEN it animates smoothly
- WHEN I view on mobile THEN chart is responsive

### US-3: View Recent Tasks List
**As a** user  
**I want to** see my most recent tasks  
**So that** I can quickly access current work

**Acceptance Criteria:**
- WHEN I view dashboard THEN I see 5 most recent tasks
- WHEN I click a task THEN I navigate to task detail page
- WHEN I have no tasks THEN I see empty state with "Create Task" button
