Concertina Columns

Requested tag: module:concertina-columns

This name is not implemented as a module in the checked 2026 theme. Adding the tag does not create columns of accordion items; it can fall back to ordinary Basic content. An example heading in the shared style guide is not confirmation that the module is available.

Use Concertinas for expandable questions and answers. Add layout:pattern-right when the design calls for the accordion stack beside the fixed woven pattern.

DEV TODO: If the signed-off design needs actual concertina columns, For Purpose needs to implement and verify that layout before CMS setup instructions can be completed. Record the final tag and its content fields here once that work is done.
