When two shapes meet, the trailing axes must equal or be 1. A mismatch is not a mystery — it is a broken colonnade. Interactive mismatch highlighting is planned.

How to read a tensor
Six pages was the plan. Four stand here as a nave; diagrams stay schematic until the workbench grows hands.
Einsum
Subscripts name axes. Repeated letters contract; omitted letters reduce. The live diagram (nodes as polygons, edges as sums) remains behind the veil.
Embeds
iframe and a tiny JS widget will freeze a tensor view into docs. Free embeds carry a TensorGon watermark; Pro removes it. The shell route already exists.
Limits
This layout build caps arrays at 4096 elements and draws only the trailing plane of higher-rank tensors. WebGPU and .npy land later.

Attention-head walkthrough
A worked QKᵀ example with temperature and causal mask will occupy this alcove — not in the layout cut.
