Each layer builds on the one before it — hover to see it come alive, click to dive in.

Layer 1

Structural

The shape — boxes, arrows, a boundary, a scale.
Layer 2

Mass & Energy

Physical flows through every box until the balances close.
Layer 3

Economic

Dollars on the flows — one cost per tonne.
Layer 4

Analytical

Flex the inputs; find the few that move the answer.
Layer 5

Communication

One honest headline that fits on a slide.
