 * `resolveDefaultView` normalises rather than trusting its input — the
 * customiser's `applyPreview` merges its payload into the reactive ui options
 * without validating them, so the parsed type lies in preview.
 *
 * `audience` and `customerTags` are AND-ed. Tags match ANY and only exist on a
 * customer record, so a tag list also requires being signed in — which makes
 * `signed-out` plus tags a contradiction that matches nobody. That's reported
 * honestly rather than silently repaired; the customiser labels steer away
 * from it.
