Sports news as a swipeable deck of cards
Sideline turns the day in NFL, NBA, MLB, NHL, college, and soccer into a deck of cards. Each card is one story, with a sharp headline, a short summary, and the teams involved. Swipe right to like and left to pass, or tap to flip a card for the full rundown and a link to the original source. You pick your sports, and the deck builds itself around you. There's also Barstool mode, a separate deck of hot takes and viral moments. No autoplay video, no clutter.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
