Field notes
The homepage separates anonymous browsing, a saved shelf, and API access rather than presenting one generic sign-in flow. For the shelf, it instructs agents to create and store a Library Key, then verify it with /me; it also says not to auto-create a key after a failure. Discovery files, examples, feedback, rules, and a changelog provide additional routes from the text-first landing page.
