Can I vibecode June?

Build a focused B2B product analytics and health tracking platform inspired by June.
Stack: Next.js 15, TypeScript, Tailwind CSS, PostgreSQL, and Prisma/Drizzle.

### Core Features to Implement:
1. **Company/Account-Level Analytics:**
   - Shift focus from individual users to account-level health.
   - Build dashboards that aggregate usage data by Company/Organization.
   - Track activation, retention, and feature adoption at the account level.

2. **Auto-Generated Reports:**
   - Create "out-of-the-box" reports that generate automatically upon data ingestion.
   - Implement an Activation Funnel, Cohort Retention chart, and Feature Usage trends.

3. **Churn Prediction & Health Scoring:**
   - Implement a customizable Health Score algorithm based on activity frequency and feature usage.
   - Create a dashboard for Customer Success teams highlighting "At-Risk" and "Power User" accounts.
   - Build a Milestone tracking system to monitor users hitting specific activation criteria.

4. **Event Ingestion & Management:**
   - Build a lightweight HTTP API endpoint to ingest custom JSON events (e.g., `track('Feature Used', { companyId, userId })`).
   - Allow manual CSV import of event data for historical analysis.

### Technical Requirements:
- The app should be self-hosted and fully private.
- Provide a clean, modern, and highly visual UI with interactive charts (e.g., Recharts or Chart.js).
- Exclude enterprise governance, real CRM integrations (Salesforce/HubSpot), and massive scale distributed processing.
- Provide a README with setup instructions, database schema details, and example cURL commands for sending events.
