Suggested and Serendipity sit on the cards

Discovery used to sit between the hero and the catalog as its own reel. It fought the page. The same picks now live on the subject cards: a Suggested pill, or a small heart for Serendipity.

Suggested is from what you have already opened, diversified by category, with at most one tech subject in the set. Serendipity is outside those categories — and not tech if the suggestions already have tech.

How you arrived at a subject is not how you study it. The badge is a hint. The lesson is still the definition, the essentials, an example, and a check.
