Data attributes
AgentsKit UI components are headless. Every stylable hook is a data-ak-* attribute so your CSS (or your LLM) can target them reliably.
Components emit zero styles. They emit data attributes. Style with your favorite CSS stack; generate UI with an LLM and the attributes tell it exactly where to hook.

#Generative UI
Because selectors are stable and framework-agnostic, LLMs can generate CSS / className overrides that work cross-framework. See Generative UI recipe.
