Extended Support Cost Tracker.
Surfaces every resource on an engine version that has moved into paid AWS Extended Support, with the indicative list-price difference between standard and extended-support rates. v1 is deliberately catalogue-level — no Cost Explorer math; that's a Business+ tier feature for v2. The point is to make the customer aware of the premium, not to compute exact monthly cost down to the dollar.
Single column
Full-width pane — typical for a finance-team dashboard. Hero count, embedded table with engine / standard rate / extended rate / Δ%, expandable per-engine drill-downs with affected resources and upgrade-guide link.
Two columns
Same pane embedded twice — multi-account portfolio view.
Production AWS account.
Staging AWS account.
