:sig
String component(String name, [DTree props], [Request& context])

:desc
Renders another `.uce` file as a component and returns the captured output as a `String`.

`component()` resolves the target file relative to the current page and also tries the `components/` prefix automatically, mirroring the shorthand used by the web app starter example project.

Component props are passed in `context.call`.

Because `<?= ... ?>` HTML-escapes its value, embed component markup with `<?: component(...) ?>`, `print(component(...))`, or use `component_render(...)` for direct output.

When `name` contains a colon, such as `components/card:BODY`, the part after the colon selects a named component handler exported from the component file through `COMPONENT:BODY(Request& context)`.

The default handler is `COMPONENT(Request& context)`.

When `name` starts with a colon, such as `:BODY`, the target resolves against the current `.uce` file so component files can call their own named handlers without repeating the file name.

Resolution order is:
exact file name
exact file name with `.uce`
the same two forms under `components/`

Example:
`DTree props;`
`props["title"] = "Status";`
`&lt;&gt;&lt;?: component("workspace/panel", props, context) ?&gt;&lt;/&gt;`
