Can Knapsack support static site requirements beyond the design system content?

Yes; the goal is for Knapsack to be a single, central source of truth for your teams to access everything they need from the system, be it contribution guidelines, design assets, tokens, or coded components. For Enterprise customers, we're able to customize the application experience quite extensively, as well, which can allow us to provide tailored experiences based on their unique requirements. Contact us to discuss what you want to achieve and the best path to get there. In the meantime, here is some documentation on out-of-the-box features for creating documentation and embedding resources.
