# Install and place "number-004" (Percent Guard) 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/number-004.json

Registry item: https://vibeui.ru/r/number-004.json
Installs to: components/vibeui/number-004.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 percent input that will not silently clamp 150 to 100: the wrong number stays in the field, gets highlighted and explained in words.

A percent field with honest 0–100 validation: the error is not hidden by autocorrection, it is highlighted and captioned. Zero dependencies, one file.

## 3. How to use it
import { Number004 } from "@/components/vibeui/number-004"

<Number004 label="Discount share" defaultValue={15} error="A percent only goes from 0 to 100." />

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-number-004-* palette — do not swap it for your theme tokens
- its own light surface: the field gets shown over any background
- the refusal to clamp silently: 150 instead of 15 is a typo, and rewriting it to 100 hides it all the way to checkout
- the data-invalid and aria-invalid pair: the highlight has to be mirrored for screen readers
- aria-live on the explanation: the error text changes without a reload and must be announced
- storing the value as a string — otherwise an in-progress empty field collapses to zero
- the bar under the field: a share reads faster as an area than as a digit

## 6. You may change
- label — the field caption
- defaultValue — the starting percent
- error — the error text under the field
- the wording of the calm-state hint
- the accent through the accent prop

## 7. Rules
- The component does not block submission: check invalid on your side before submit.
- The bar is capped at zero and a hundred even for invalid input — otherwise it escapes the frame.
- A fractional percent is allowed on input, but the hint rounds the remainder to a whole number.
- 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/number-004.json
https://vibeui.ru/r/number-004.json

Компонент самодостаточен: один файл, ноль зависимостей, палитра в локальных переменных --vibeui-number-004-*. Клиентский: значение и признак ошибки живут в состоянии. Ввод хранится строкой, поэтому промежуточное пустое поле не превращается в ноль. Выход за 0–100 не исправляется автоматически: он помечается data-invalid на корне, aria-invalid на поле и текстом в области aria-live. Полоса под полем показывает долю площадью — процент так считывается быстрее цифры.

Component source

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

"use client"

import { useId, useState } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Number004Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "defaultValue" | "onChange"
> & {
  label?: string
  defaultValue?: number
  error?: string
  accent?: string
}

// Идея компонента: процент, который не зажимается молча. 150 вместо 15 —
// это опечатка, и подменять её на 100 значит спрятать ошибку: пользователь
// увидит верное на вид число и уедет с неверными данными. Поэтому выход за
// 0–100 остаётся в поле, помечается aria-invalid и объясняется словами.
// Полоса под полем показывает долю сразу: проценты воспринимают площадью.
