The landing/marketing page for this looks like something someone promoted/vibe coded including the Bob mascot. Looks awful from a design perspective. Had to double check that this was the actual IBM domain
They have a decent component system with Carbon[0] and a whole design principles website[1] which they could have easily pointed their LLM of choice to.
Even the ibm.com landing page isn't close to the design system spec, rounded corners and whatnot...
