Guides
Workflow patterns and rules. Read these before shipping.
These pages cover the things experience teaches you that the API reference can't. Read them once before your first publish.
Best practices
The non-obvious rules that prevent production incidents.
Subscriptions
Lifecycle, cleanup, framework patterns. The single most common bug class.
Capability detection
`client.has()` so an older host without a family doesn't crash your UI.
Multi-display mini-apps
Render on the passenger screen, drive the cluster, build for cars with 1, 2, or 3 screens.
Error recovery
From `e.code` to the right user-facing recovery — retry, fallback, or report.
Testing
`MiniAppClient.withBridge()` is the one seam you need.
Type-only imports
When to use `i99dash/types` vs the main entry.
