HoverData
Import from @pibbl/core/viz. Evaluates an ordinary synchronous query and renders its typed result.
query(context) reads current signals and context.scale(id) snapshots. Its synchronous result (including undefined) goes to children(result). Callbacks cannot call hooks or write signals; return components for hooks. Query function identity does not determine child identity. The context cannot be retained.
