# Install and place "switch-009" (Day Night Switch) 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/switch-009.json

Registry item: https://vibeui.ru/r/switch-009.json
Installs to: components/vibeui/switch-009.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 day/night theme switch: the track repaints from daylight sky to night, the sun turns into a crescent, and stars rise beside it.

A theme switch turning a sun into a crescent with rising stars, entirely in CSS. One file, zero dependencies, a server component.

## 3. How to use it
import { Switch009 } from "@/components/vibeui/switch-009"

<Switch009
  dayLabel="Light theme"
  nightLabel="Dark theme"
/>

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-switch-009-* palette — do not swap it for your theme tokens
- the crescent cut by a circle in the night-sky colour: change the track background and that circle must change with it
- the stars as a single dot with three shadows — decoration does not need three extra nodes
- the mode caption beside the thumb: a sun and moon glyph alone does not say what a tap will do
- the prefers-reduced-motion rule — the travel, the repaint and the rising stars must be switchable off
- the component's own light surface — without it the dark text disappears on a dark page

## 6. You may change
- the light mode caption through dayLabel
- the dark mode caption through nightLabel
- the focus accent colour through accent
- the sky and luminary colours in the day, night, sun and moon variables

## 7. Rules
- The component does not switch the site theme: it only reflects the choice, the state owner applies it.
- A real theme switch needs a third "follow system" mode — here there are deliberately two.
- The crescent cut depends on the night-sky colour: with a translucent background the crescent shows in daylight.
- 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/switch-009.json
https://vibeui.ru/r/switch-009.json

Серверный компонент: всё состояние держит нативный checkbox с role="switch". Месяц сделан вырезом — круг цвета ночного неба на псевдоэлементе наезжает на солнце, днём он сдвинут за пределы бегунка. Звёзды нарисованы одной точкой с тремя тенями в box-shadow и проступают правилом input:checked ~ [data-part=stars]. Подпись режима переключается через :has(input:checked). Все переходы гасятся prefers-reduced-motion. Палитра в --vibeui-switch-009-*.

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 Switch009Props = Omit<
  ComponentPropsWithoutRef<"input">,
  "type" | "size"
> & {
  dayLabel?: string
  nightLabel?: string
  accent?: string
}

// Идея компонента: переключатель темы, а не абстрактный тумблер. Дорожка
// перекрашивается из дневного неба в ночное, бегунок из солнца превращается
// в месяц (вырез сделан вторым кругом с цветом фона), а звёзды проступают
// только ночью. Всё состояние держит нативный checkbox, JS не участвует.
