budget topology
Architecture diagrams hide the shape of a system's tradeoffs. Drag infra components onto the grid; each tile reports its cost, latency, and blast radius. The Pareto frontier shows you when you've stopped buying performance and started buying regret.

how to read the map
- cost — back-of-envelope monthly USD at small-to-mid scale.
- latency — added p50 milliseconds the component contributes to a typical request path.
- blast radius — % of user-facing functionality that breaks if this single tile fails. Stateless edges are small. A single Postgres is huge.
- pareto frontier — the lower-left envelope of cost-vs-latency. Sit on it and you're paying the right amount for the speed you got. Drift above it and something cheaper would do the same job.
