scroll one line at a time, render div and details elements

not very big news here, but now you can:

• scroll just one line at a time instead of a whole renderable/element at once
• render div and details properly! now you can click on a details element to open and close it! this didn’t even take too long
• more technical, but i switched to mostly using the opentui renderable api which uses classes like TextRenderable or BoxRenderable that return a Renderable instance instead of functions like Text and Box which return a ProxiedVNode<T>. this is mostly because there’s a bunch of things a Renderable has that a ProxiedVNode doesn’t

anyways im currently working on adding footnotes, so see you in a few days
