Guides that trail your pointer

Build one interactive web page: A planning board for an invented design studio, and three named guides, Mina, Otto and Juno. Each is an arrow and a coloured name pill on a spring of its own stiffness, so they follow your pointer in a fixed order and keep gliding after you stop. Leave the board and they go to the cards and get on with their own work. The page says plainly that nobody else is here and the three are drawn by it.

Set it on an invented business called Sampleton, with its own drawn or generated pictures and no one else's files. It suits: A shared or collaborative tool that wants to show what working together looks like, a guided tour, a studio or a team page that feels inhabited. Do not let it fail the way this kind of piece usually does: Cursors that imitate other users, and tags that cover the content. Here they are labelled as the page's own guides, the tags flip away from the edge, the guides can be sent away, and reduced motion leaves them still.

It must work with the keyboard, on a phone, with reduced motion respected and no text under 12px. Tell me which libraries you chose and why.
