If anyone wants to see why this specific did:web couldn't log in. TL;DR bsky handle resolver returns the wrong DID from a stale index. Now I use the authoritative source.

Some ideas for your next post: embed your favorite song, a social media post, your own musical writing, a Mermaid diagram, an interactive graph, or hide spoilers!

We have Mermaid diagrams for all your needs. Architecture (with logos!), flowchart, sequence, Git, quadrant chart, Kanban board, and more. Easily view the source of a diagram on any post for inspiration, like this one from our series "How PiPup works".
