Ember Field
Sparks are born at the bottom, sway on their own breeze, cool from yellow to deep orange and go out. Move through them and they are pulled in and sent around the pointer; tap and a fresh handful leaps up. Colours are classes.

The decision inside it
The pointer is a current, not a magnet
Near the pointer, sparks are pulled in and sent around at once, so they orbit and stream past instead of collapsing into a clump. Each ember lives its own life, so there is never a visible loop. The count follows the area with a ceiling, and phones get fewer.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Ember Field for this.
Install it: npx shadcn@latest add @layro/ember-field
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/ember-field.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @layro registry with your CLI token: see the Namespaced tab.
When to use it
Use Ember Field for a warm, celebratory section like a launch or an event: sparks rise from a glow along the bottom and gather around the pointer.
Usage
import { EmberField } from "@/components/ui/ember-field";
export function LaunchWeek() {
return (
<EmberField className="h-[480px] bg-neutral-950">
<div className="flex h-full items-center justify-center text-white">
<h2 className="text-5xl font-bold tracking-tight">Five days. Five launches.</h2>
</div>
</EmberField>
);

max | number | Hard ceiling on sparks. Default 260. |
