We don't have a panel requirement for comics. It's up to the creator to decide how many panels are needed to convey their idea. The "30 panels per episode" is a rough estimate we give for long-form narratives.
The production schedule is dictated by the creator but we work with creators to have a backlog of episodes (a period where creators make episodes but we don't publish yet) so we can eventually consistently publish at least 2 episodes a month.
A typical season for a series on our platform is about 24 episodes so we ask for stories that are submitted to the Incubator program to have, at the very least, 20 episodes.
It's definitely okay to write three paragraphs for that section, if you want. There's no minimum or maximum requirement for that section. All we ask is that you're able to convey to us the message you want readers to have when they read your story.
A season of a webcomic is similar to a season of TV in which a plot unfolds episode-by-episode. As stated previously in our Newsfeed post, a season will have about 20-25 episodes. And it's difficult to give an estimate for pages per episode as we don't usually work in page format. A good rule of thumb is an episode should cover a narrative beat.
