Mix Rebalancer

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/mix-rebalancer.tsx.

Install the pastetaste component "Mix Rebalancer" (mix-rebalancer) into this Next.js project and use it.

What it is: A mixer where switching items on and off and dragging one weight slider rebalances all the others so the total stays 100%, with a live donut, blended return, risk label and a compounding projection.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/mix-rebalancer.json
   (it writes components/pastetaste/mix-rebalancer.tsx; install any npm packages it reports).
2. Import it: import { MixRebalancer } from "@/components/pastetaste/mix-rebalancer" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- items: MixItem[] = 7 sample assets — { id, name, tag, ret (% per year), risk (0-100) } for every item that can be switched on.
- presets: { label: string; weights: Record<string, number> }[] = 3 mixes — Quick-start mixes; each weights object must add up to 100.
- defaultWeights: Record<string, number> = first preset — Initial active items and their weights (sum 100).
- maxActive: number = 6 — Most items that can be active at once.
- stake / years / currency: number / number / string = 10000 / 10 / '€' — Inputs of the projection line.
- palette: string[] = ink and blues — Donut and legend colours in the order items are switched on.
- className / style: string / CSSProperties — On the root.

Then run the dev server, check it in the browser at desktop and mobile width, and tell me the page URL.
