Cards have a header, optional subtitle/icon, and sections. Sections, separated by horizontal rules, contain UI widgets, and large sections collapse. Add-ons use multiple cards for navigation, presented as a list of headers. Basic navigation provides automatic back arrow functionality. Each card section can hold a maximum of 100 widgets, and a card can hold no more than 100 card sections.\n"]]
