Summarizes the metadata of sideview cards (table names, dimensions, column
names, types, value ranges for numerics/dates, sample levels for factors, and
unique samples for characters) without leaking full raw row data or records.
Non-tabular widget cards and NULL data are handled safely.

- cards
A sideview_card, a list of sideview_cards, or tabular data.
