"""
Project Health Dashboard

Aggregates project metrics across timeline, budget, scope, and quality dimensions.
Calculates composite health scores, generates RAG (Red/Amber/Green) status reports,
and identifies projects needing intervention for portfolio management.

Usage:
    python project_health_dashboard.py portfolio_data.json
    python project_health_dashboard.py portfolio_data.json --format json
