//!   <p><strong>Share your design system in a tiny universal package.</strong></p>
//! </div>
//!
//! Dilla is a fast but minimal WASM builder based on the syntax and behavior
//! of the [Jinja2](https://jinja.palletsprojects.com/) implemented on top of
//! [Minijinja](https://docs.rs/minijinja/latest/minijinja). The goal is to
//! be able to pack your design system into a <strong>universal</strong>
//! package, executable through a simple <strong>declarative API</strong>, for
//! both server side and headless rendering.
//!
//! To know more about Dilla visit our website [dilla.io](https://dilla.io).
