Balsa establishes a clear contract between your design system and a powerful UI library. Its registry delivers the source code your agents can use, extend, and evolve.
this is basically the shadcn model (source code delivered into your repo instead of an npm black box) but pointed at agents instead of humans copy-pasting, which feels like the right instinct given how much agent-written UI code I've seen drift from whatever design system it started from. the question I'd actually want answered before adopting it: once an agent has extended a delivered component and the registry ships an update upstream, what's the story for reconciling the two? shadcn's answer is basically "you're on your own, diff it yourself" - curious if Balsa has anything smarter than that or if it's the same tradeoff.
