# llimphi-lottie

A thin bridge between `velato` (Linebender's Lottie player) and Llimphi.

`llimphi-svg` covers arbitrary *static* vector art (`.desktop` icons, logos).
`llimphi-motion` covers motion *generated by code* (tweens over the Elm loop).
This crate covers the gap in between: **vector animation authored elsewhere** —
the Lottie `.json` files designers export from After Effects / lottiefiles
(animated icons, illustrations, empty states, onboarding).

It is the twin of `llimphi-svg` with a time axis: `velato` parses the JSON into a
`Composition` and, for a given `frame`, emits into the **same** `vello::Scene`
that `llimphi-raster` uses.

## Use

```ignore
use llimphi_lottie::LottieAsset;
use std::time::Duration;

// Parse ONCE (when loading the app):
let anim = LottieAsset::from_str(include_str!("spinner.json")).expect("valid lottie");

// The app keeps the elapsed time in its state and advances it with the Elm
// loop — exactly the pattern of the simulation workers:
//   handle.spawn_periodic(Duration::from_millis(16), || Msg::Tick);
```
