Chunking
A process by which individual pieces of an information set are broken down and then grouped together in a meaningful whole.
The design-system take
Where the principle shows up in a token, component or pattern decision.
Phone numbers, card numbers and dates are chunked because raw strings are unmemorable; apply the same grouping to IDs, codes and dense tables.
