Child

Render a single entry of node's children, so a component can own placement instead of delegating it to Children — e.g. Row { node.children.forEach { Child(it) } } or a custom Layout with its own measure/place pass. An element child renders through the full node pipeline (styles, nested components, its own children); a text run renders as a joy-dom text node with its inherited text context.

Placement-only escape hatch: the parent's flex semantics (order, grow/shrink, position: absolute extraction) are NOT applied — the caller's layout owns them. A child with display: none still renders to nothing, matching the built-in dispatch.
