## Use it in a design

```yaml
nodes:
  - { id: "ledger", component: "ledger" }
```

## Source (`component` YAML, verbatim)

```yaml
# yaml-language-server: $schema=../../schema/component.schema.json
# The vendor-neutral ledger: the kind itself, with no product behind it. It sets no
# defaults and adds no properties, so every required kind property stays required on the node.
