Forkline

You are building a complete dashboard app screen with Loopkit: the "Forkline" template.

Goal: A dashboard for A/B experiments: every experiment by state, each variant's lift with a 95% confidence interval, cumulative results, guardrail metrics that block a ship, and a setup form that starts with the hypothesis.
Audience: Growth, product and data teams running experiments on AI features and product changes.

Stack: Next.js App Router, TypeScript, Tailwind CSS v4, framer-motion. Colour tokens are shadcn's plus Loopkit's --signal, --ok, --warn, --info (see https://loopkitui.com/docs/theming). Light theme by default, dark via the .dark class.

1. Install the Loopkit components this page uses:
   npx shadcn@latest add https://loopkitui.com/r/dash-kit.json   # dash-kit
2. Create app/page.tsx with the source below. Keep the section order and the copy structure; replace the product name, copy and links with mine.
3. Check it at 360, 768, 1440 and 2560 px wide, in light and dark, with reduced motion on and off. The console must be clean.

Page source:

```tsx
"use client";

import * as React from "react";
import {
  DashShell,
  Panel,
  Kpi,
  AreaChart,
  DataTable,
  Pill,
  Seg,
