🔧 Integration Steps

1. Frontend (30 min)

// Add to SubscriptionPage.tsx
import { UsageMetricCard, ROICalculator } from '@/components/subscription';

// Fetch usage forecast
const { usage } = useSubscription(); // See integration guide

// Render components
<UsageMetricCard {...props} />
<ROICalculator {...props} />

2. Backend (15 min)

# services/tenant/app/main.py
from app.api import usage_forecast

app.include_router(usage_forecast.router, prefix="/api/v1")

3. Cron Job (10 min)

# Add to crontab
0 0 * * * python services/tenant/app/cron/track_daily_usage.py

4. Analytics (10 min)
