You build on two surfaces, and every page in these docs is about one of them.

A workbook is the artifact you ship — a single .org file that renders and runs, published as a self-contained .html. It's the output: a live document that is also a program.

A toolkit is the capability you build to make a workbook (or an agent) do more — sandboxed WASM, authored in any language, run isolated, distributed as a workbook.

  WORKBOOK  the document that runs        ← what you ship
  TOOLKIT   the capability it can call     ← what you build to extend it

They compose: a toolkit travels inside a workbook (the bundle carries its compiled WASM), and a workbook's HTML can call a toolkit live through the Dock. Distribution is the document — installing a toolkit is installing a workbook.
