Buyers can include these topics in `userBiddingSignals` when defining interest groups, allowing `generateBid()` to factor them into bids. Sellers can add topics to `auctionSignals`, `sellerSignals`, or `perBuyerSignals`, enabling `scoreAd()` to consider user interests. The Topics API returns a selection of observed topics for the browser, which can be used directly or processed with other data in bidding logic.\n"]]
