Components
Every component the library ships has a page here — a playground, worked examples, and the props read straight off the source. Nothing on this list sends you somewhere else to find out what it is for.
Patterns go the other way: several of these arranged into one screen fragment you can copy whole.
Storybook is generated from the same files and stays in step with them by construction. Reach for it to see one component under every combination of its props at once, which is a different question from the one a page answers.
