<h2>What it is</h2>
<p>
Decodal is a small data language for configuration shapes that need validation, defaults,
lazy imports, and predictable composition.
</p>
</article>
<article class="home-card">
<h2>Where it runs</h2>
<p>
Use the Rust crate for runtime embedding, the WASM package in browsers, CodeMirror/Lezer for Web editing
and formatting, and Tree-sitter for general editor integration.
</p>
</article>
<article class="home-card">
<h2>Start here</h2>
<p>
Open the playground to run examples in your browser, or read the components page to see how the runtime and
editor pieces fit together.

Constraints and defaults are values. Compose them with concrete data and materialize when the host knows what
output shape it expects.
