Anatomy of a node page
Every node entry follows the same shape so you can skim:
- What it does, one sentence.
- When to use it, typical scenarios.
- Inputs, the input ports and what they expect.
- Outputs, the output ports and what they emit (schema or example).
- Configuration, every field, with type and default.
- Example, a minimal working config.
- Notes & gotchas, anything non-obvious.
