 Keep the protocol shape provider-agnostic. Do not add provider-specific renderers for new limit windows; labels and generic bars should carry the UI. API responses should be parsed and normalized with Zod inside the fetcher, while the protocol boundary stays strict so old/new client compatibility is explicit.
