## How To Read This Section

- Start with [Matrix plugin architecture](matrix-plugin-architecture.md) for host/plugin
  ownership.
- Use [system design](system-design.md) for runtime/web/platform flow.
- Use [architecture overview](../architecture.md) when you need the older Flow-centric mental model
  behind the runtime and session layers.
