Explore lists its studysets in a grid as the library does: each card in the studyset's colour along the top, its title under its secondary title, the start of its description and what it holds, then, quieter, its author's handle, the release and the licence, and a compact Add. A tap opens the summary, which shows the colour too. The Publish sheet has a Description on Explore, starting from the latest release's, else the studyset's own, and sent with the release: a studyset may introduce itself to strangers while its own description stays empty in the library.
