///
/// Until item 53 this class also painted a row-wide strip of tag chips after
/// the cells, because a delegate cannot paint outside its column and the strip
/// spanned all five. With one column and one delegate painting the whole card,
/// that reason is gone and so is the paintEvent, along with the two faults it
/// kept producing: a deleted row cut in half, and every other row showing a
/// bare stripe, both from the view having to re-honour alternating colours,
/// the selection and BackgroundRole across cells it did not own.
