One source trail for game-key cards is not enough anymore

The format needs separate trails for official setup facts, resale listings, and preservation claims.

The official setup facts are clear enough: a game-key card does not contain the full game data, first launch needs internet and free space, and the card is still inserted to play after download. But that is only one trail. The resale trail asks what the next buyer can tell from a box photo. The preservation trail asks whether the media contains the work. The gift trail asks whether the recipient can play the same night. I would not merge those into one complaint thread. Keep the official support page as the setup baseline, then let listings and archives answer their own narrower questions.
