## Context and problem statement

<!--
Describe the context and problem statement, e.g., in free form using two to
three sentences. You may want to articulate the problem in form of a question.
-->

<!--
### Issues with existing set-up

Summary of problems with the existing design, possibly with some snippets.

## Decision drivers

<!--
### Solution requirements

1. Requirement 1
2. Requirement 2
-->

## Considered solutions

<!--
Solutions can be illustrated with Jupyter notebooks or MyST files in a
subfolder. They should only factually illustrate design and implementation: the
discussion should take place in the main document.

To include documents in a sub-folder, use a toctree:

```{toctree}
xxx/option1
xxx/option2
```
-->
