+
+## 🎯 Objectives Completed
+
+### 1. Replace Raw Giant Token Counters with Sparkline/Trend Visualizations
+- ✅ **Token Sparklines**: Interactive mini-charts showing token usage trends over time
+- ✅ **Dynamic Color Coding**: Sparklines change color based on usage patterns (green for stable, red for spikes)
+- ✅ **Hover Tooltips**: Detailed information on hover with formatted token counts
+- ✅ **Trend Indicators**: Visual arrows and percentages showing usage direction
+- ✅ **Real-time Updates**: Charts update automatically with LiveView data
+
+### 2. Add Per-Issue Budget Views with Visual Progress Indicators
+- ✅ **Budget Gauges**: Circular progress indicators showing budget utilization
+- ✅ **Percentage Display**: Clear percentage usage shown in gauge center
+- ✅ **Color-coded Status**: Green (healthy), amber (warning at 75%), red (danger at 90%)
+- ✅ **Budget Allocation**: Configurable budgets per issue type (20k for standard, 50k for features)
+- ✅ **Remaining Tokens**: Display of tokens remaining within budget
+
+### 3. Implement Anomaly Highlights for Unusual Token/Runtime Spikes
+- ✅ **Automated Detection**: Algorithm identifies issues with >2x normal token usage
+- ✅ **Visual Highlighting**: Red border and background highlighting for anomalous issues
+- ✅ **Warning Indicators**: ⚠️ icons with tooltips explaining the anomaly
+- ✅ **Pulse Animation**: Subtle animation to draw attention to problems
+- ✅ **Configurable Thresholds**: Adjustable spike detection sensitivity
+
+### 4. Create Interactive Trend Charts for Token Consumption Over Time
+- ✅ **Dual-axis Charts**: Combined token usage and runtime visualization
+- ✅ **Chart.js Integration**: Professional charting library with smooth animations
+- ✅ **Interactive Legends**: Clickable legend items to show/hide datasets
+- ✅ **Time Series Data**: 24-point historical data simulation
+- ✅ **Responsive Design**: Charts adapt to screen size and view mode
+
+### 5. Add Budget Allocation and Utilization Tracking
+- ✅ **Budget Overview Panel**: Aggregate view of all issue budgets
+- ✅ **Utilization Metrics**: Total allocated, used, and remaining budgets
+- ✅ **At-Risk Alerts**: Dashboard section highlighting budget-constrained issues
+- ✅ **Burn Rate Calculation**: Estimated tokens consumed per hour
+- ✅ **Remaining Time**: Projected hours until budget exhaustion
+
+### 6. Ensure Mobile Compatibility with New Card/Table Modes
+- ✅ **Responsive Sparklines**: Smaller charts on mobile (80x24px vs 120x32px)
+- ✅ **Card View Integration**: Budget gauges replace token numbers in card mode
+- ✅ **Touch-Friendly Charts**: Optimized touch targets and hover states
+- ✅ **Mobile CSS**: Dedicated responsive breakpoints for chart layouts
