Follow these steps when you write or change a recipe.

1. Read recipe-v1.md first.
2. Give every part an id that says what it is, such as tree-3-trunk.
3. Stay inside the budget.
4. To make things move together, define a rhythm once in rhythms and have many parts follow it. Avoid giving every part its own separate motion.
5. To change an existing world, send an edit transaction. Do not rewrite the whole recipe. Only the things you were asked to change should change.

Blank's own tests check the examples: every recipe here builds, and every edit applies.
