The single place this package knows that Field has a screen — and it is one function long.

Each printer registered here reduces its value to one of the plain summary data classes in Summaries.kt — PolytopeTopologySummary, Polytope4Summary, and so on — and hands that to Field's ordinary reflective value visualizer. So a topology, a transform result or a canonicalization plan left as a box's last expression prints something useful, while nothing in the topology depends on FLine, meshes or a renderer, and println(x.summary()) shows the same facts because it is the same value.

fun registerPolytopeVisualizers()

Register a value printer for each polytope type that has a summary, so live boxes print something useful without importing a visualizer.

Called by Field for you — @RunsAt(newRoot) runs it once when a document root is created — and harmless to call again, since registration is keyed by class in a process-wide map and simply replaces. Each printer runs its summary on demand, which for the topology-bearing types means running PolytopeTopology.validate, so a printed value is a fresh verdict rather than a cached one.

@RunsAt(newRoot)
fun registerPolytopeVisualizers() {
    registerValuePrinter<PolytopeTopology> { it.summary().h }
    registerValuePrinter<Realization3> { it.summary().h }
    registerValuePrinter<PolyhedralObject> { it.summary().h }
    registerValuePrinter<ValidationResult> { it.summary().h }
    registerValuePrinter<TransformDeployment> { it.summary().h }
    registerValuePrinter<PolytopeTransformResult> { it.summary().h }
    registerValuePrinter<TriangulatedGeometry> { it.summary().h }
    registerValuePrinter<CombinatorialOrbits> { it.summary().h }
    registerValuePrinter<RelaxationPlan> { it.summary().h }
