It also updates `get_stack_contents` and `get_card_content` to return complete ACO fields in their responses and extends `capsule_from_content` with a `save_as: 'stack'` option for creating enriched stacks directly.","image":null,"stack":{"id":"2e5d1345-7144-4a10-b34a-9d11a4eba127","title":"ACP","url":"https://stacklist.com/c/technology/stack/2e5d1345-7144-4a10-b34a-9d11a4eba127"},"created_at":"2026-04-20T13:50:04.520Z","updated_at":null,"aco":null,"_links":{"self":"/api/public/card/62c1adfc-b911-443c-aa79-0482ee5508f3.json","html":"https://stacklist.com/card/62c1adfc-b911-443c-aa79-0482ee5508f3","md":"/api/public/card/62c1adfc-b911-443c-aa79-0482ee5508f3.md","stack_json":"/api/public/stack/2e5d1345-7144-4a10-b34a-9d11a4eba127.json"}}
