# PlanRunner
An agent plan card that people review, edit and reorder, then watch run with pause, skip and stop.
## 1. Setup
// npm install framer-motion
File: components-workspace/plan-runner/index.tsx · 'use client' · export default function PlanRunner(props: PlanRunnerProps)
Tailwind CSS v4, with the dark: variant following your theme. Colors come from the component variables in THEME_VARS.
The @/app/_icons imports are the AI Canvas icon set. Without it, use any icon components that accept size, weight and SVG props, with a matching IconProps type.
