Show Details: the source list and the indices of its records behind the value cell at
(row, col) of the report grid (relative to its top-left), in source order. None when
that cell holds no value (a label, a header, a blank). An error, for any cell, when the report
on the sheet is no longer what the source computes: the cell’s records would be another cell’s.
