ferro-json-ui 0.3.7

//! Built-in JavaScript runtime for ferro-json-ui (split per concern).
//!
//! Each submodule contributes one `setup*` function. The assembled bundle
//! wraps them in a single IIFE with a `ferroRuntime()` dispatcher invoked
//! on DOMContentLoaded. The emitted output is a single string — no extra
//! HTTP requests.
