Turn YUI models into a working frontend and its rendering/input adapters.

```yh
external BuildYuiAuthoredApplicationDisplayList(yuiAuthoredRuntime original runtime, yuiThemeDefinition original theme, yuiAuthoredApplicationLayoutPlan original plan, text hoveredNodeId, text pressedNodeId, text focusedNodeId) returns yuiDisplayList
```


## Use BuildYuiAuthoredApplicationDisplayList

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using frontend.yui

// Turn YUI models into a working frontend and its rendering/input adapters.
yuiAuthoredRuntime runtime = yuiAuthoredRuntime("id")
yuiThemeDefinition theme = yuiThemeDefinition("id", "display Name", "mode", "example")
yuiAuthoredApplicationLayoutPlan plan = yuiAuthoredApplicationLayoutPlan(1, 1, 1, 1, true, 1, 1, 1, 1, 1, 1, yuiLayoutRect(1, 1, 1, 1), "root Id", [], [], [], "diagnostic")
text hoveredNodeId = "hovered Node Id"
text pressedNodeId = "pressed Node Id"
text focusedNodeId = "focused Node Id"
yuiDisplayList result = BuildYuiAuthoredApplicationDisplayList(runtime, theme, plan, hoveredNodeId, pressedNodeId, focusedNodeId)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/frontend.yui--BuildYuiAuthoredApplicationDisplayList/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
