    Values of Tableau's MarkType enum: the primitive one marks card drew.

    Mirrors MarkType in ExternalContract/Shared/Namespaces/Tableau.d.ts — all thirteen members, verbatim.

    There is no Automatic member. "Automatic" is an authoring-time setting; by the time a viz is drawn Tableau has resolved it to one of these. The enum is closed in this contract version, which is not the same as closed forever — the host page loads whichever Embedding build it likes — so extractor.ts still routes an unrecognised value to the heuristic ladder instead of treating the union as exhaustive at runtime.
