//! Templates, the functions plugins put in them, and themes.
//!
//! Everything here needs the plugin runtime, but only for the one thing it
//! uniquely provides: running a template function. Resolving the environment
//! chain and deciding what a render should do about errors are ordinary work
//! and stay here, where every host gets them the same.
