# Install and place "buttongroup-029" (Theme Swatches) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/buttongroup-029.json

Registry item: https://vibeui.ru/r/buttongroup-029.json
Installs to: components/vibeui/buttongroup-029.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
A theme picker made of interface swatches instead of a sun and a moon: "system" is cut diagonally with clip-path — half light, half dark.

A theme picker built from interface thumbnails, including a half-and-half "system" swatch. Zero dependencies, one file, a server component.

## 3. How to use it
import { Buttongroup029 } from "@/components/vibeui/buttongroup-029"

<Buttongroup029
  lightLabel="Light"
  darkLabel="Dark"
  systemLabel="System"
  defaultValue="system"
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-buttongroup-029-* palette — do not swap it for your theme tokens
- the swatches' own colours: a thumbnail inheriting the page theme vanishes into its own background
- the diagonal cut on "system" — it explains the option without a caption
- the caption under every swatch: not everyone tells "system" from "dark" at a glance
- the box-shadow matching the selected border: a single border looks thinner than its neighbours
- radios inside a fieldset — a theme choice must work with arrows and reach the form

## 6. You may change
- the option captions through lightLabel, darkLabel and systemLabel
- the initial theme through defaultValue
- the accessible group name through label
- the form field name through name and the selection colour through accent

## 7. Rules
- There are exactly three options: a fourth swatch has to be drawn by hand.
- The component does not switch the theme: your code applies it after submit.
- The swatch stripes are aria-hidden decoration — there is no point adding text to them.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/buttongroup-029.json
https://vibeui.ru/r/buttongroup-029.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в переменных --vibeui-buttongroup-029-*. Серверный: выбор держат radio внутри fieldset. Каждый сегмент несёт миниатюру интерфейса: рамка, три полоски «текста» на абсолютных позициях и заливка. Тёмный образец меняет и фон, и цвет полосок; «системная» получает ::after с clip-path:polygon(100% 0,100% 100%,0 100%) — диагональ объясняет «как в системе» без слов. Образцы держат собственные цвета, не зависящие от темы страницы: иначе светлая миниатюра исчезла бы на светлом фоне. Сегменты не сцеплены, они стоят карточками в grid с gap; выбранный получает рамку и box-shadow в тот же цвет, чтобы линия не выглядела тоньше соседних.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Buttongroup029Props = Omit<
  ComponentPropsWithoutRef<"fieldset">,
  "children"
> & {
  lightLabel?: string
  darkLabel?: string
  systemLabel?: string
  defaultValue?: string
  label?: string
  name?: string
  accent?: string
}

// Идея компонента: выбор темы, где каждый сегмент показывает не значок
// солнца или луны, а сам образец — миниатюру интерфейса с полосками текста.
// «Системная» нарисована диагональным разрезом clip-path: одна половина
// светлая, другая тёмная, и это честно объясняет «как в системе» без слов.
// Образцы держат собственные цвета, не зависящие от темы страницы: иначе
// светлая миниатюра исчезла бы на светлом фоне.
