The governed set of DATA-KINDS a personalization field's input can take — the shape of the value the buyer supplies, region-neutral (a text box, a number, a date, an image upload mean the same everywhere; the set names the input's shape, not a locale or a purpose). Every member is a value the buyer SUPPLIES openly; a pick-one from a seller-listed set is deliberately NOT a member — a set of offered options is a variation axis (a cardinality-many token property the catalogue may realise into cells), not a personalization input (adversary A11, 2026-07-20). A tight, growing set (L13): the field's PURPOSE (engraving, monogram, gift message) is carried by its label, not by a member here — those are all the free-text data-kind under different labels, so the set does not sprawl one member per surface-name.

Answers the question: input type.
