1//! The boundary between the framework and the script module of the
2//! platform.
3//!
4//! One file per group of functions, as the script module groups them. Each
5//! holds the imports (functions of the script module, called from here) and
6//! the exports (functions of the framework, called by the script module).
7//! Objects of the page are opaque [`JsObject`] handles; nothing outside this
8//! module and the render targets touches them except to pass them back.
9//!
10//! [`thread_proxy`] is the one file that is not about the script module: it
11//! crosses from one thread of the module to another, and asks the script
12//! only for what the runtime carried to the main thread.
