This section holds short, copy-pasteable recipes, one goal per page. Recipes assume the concepts and link back to the architecture or theory rather than re-teaching everything from scratch.
Current recipes:
For atmosphere work, read Atmosphere capabilities first if you need the dataset matrix and backend status. Then use the how-to pages here for the exact local conversion, query, and validation commands. Use Spectra data architecture for the runtime spectra boundary and backend design.
For broader package setup, start with Getting started. For the numerical principles behind the recipes, see Writing AD-safe scientific numerics.
