/**
 * Pure payload normalisation.
 *
 * API and event-stream payloads are coerced through here before they reach
 * any component, so an unfamiliar shape — `null`, a missing field, or a
 * field of the wrong type — produces a well-formed, renderable value
 * instead of reaching a component and throwing (design.md D23). This is
 * what the error boundary (task 1.0) is a backstop for, not a substitute
 * for.
 *
 * Every function here is a pure coercion: given anything, it returns
 * something safe to render (or, for the event stream, `null` to mean
 * "ignore this event"). None of them throw.
