A good toolkit for Ink is much needed, although Ink itself leaves something to be desired, especially compared to https://github.com/anomalyco/opentui (bun only, used by opencode)

I tried to build a Viewport component in Ink, but after scrolling to the bottom of a list of 150 rows, Ink started to render things strangely - the top line overflowed the box bounds, and a few blank lines appeared inside the viewport. I couldn't figure out where the bug was in Ink, I somewhat suspect floating point issues somewhere in the native Yoga<->JS layer?
