readText

A shape's label as plain text.

A label has two spellings on the record — props.richText, the document the store keeps, and props.text, its flattened form — and this reconciles them through readRichText so the two readers can never disagree about what a shape says.

key names a *plain-text-only* prop (a frame's name); only the default "text" participates in the reconciliation, because only it has a rich counterpart.
