# Install and place "iconstack-004" (Vertical Avatar Stack) 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/iconstack-004.json

Registry item: https://vibeui.ru/r/iconstack-004.json
Installs to: components/vibeui/iconstack-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 vertical member stack for a narrow column: it grows downwards and takes the width of a single circle instead of breaking the sidebar with a horizontal row.

A vertical member stack: overlap through column-reverse and a counted caption below. Zero dependencies, one file, no client JS.

## 3. How to use it
import { Iconstack004 } from "@/components/vibeui/iconstack-004"

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-iconstack-004-* palette — do not swap it for your theme tokens
- column-reverse instead of z-index: the upper circle lands above the lower one on its own
- tying size and overlap to one pair of variables — otherwise the stack falls apart at lg
- aria-hidden on the circles: initials mean nothing aloud, the caption carries the meaning
- the counted caption: three circles do not tell how many people are in the group
- the component's own light surface: the caption is dark and vanishes on a dark catalog background

## 6. You may change
- the circle size through size: sm, md or lg
- the caption under the stack through label
- the group roster through names
- the overlap through the --vibeui-iconstack-004-overlap variable

## 7. Rules
- A vertical stack is taller than a horizontal one: more than six circles break the column.
- Initials come from the first two words of the name: single-word handles yield one letter.
- The hue is derived from a hash of the name — renaming a member changes the circle colour.
- 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

Серверный компонент, хуков нет. Перекрытие собрано column-reverse и отрицательным margin-bottom, поэтому верхний кружок ложится поверх нижнего без z-index, а первое имя списка остаётся первым сверху — порядок чтения совпадает с порядком данных. Размер и величина перекрытия связаны одной парой переменных и переключаются атрибутом data-size, так что sm, md и lg сохраняют одинаковую плотность. Кружки декоративны и помечены aria-hidden: смысл несёт подпись с числом. Подложка светлая, поскольку подпись тёмная.

Component source

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

export type Iconstack004Props = Omit<

// Идея компонента: вертикальная стопка для узкой колонки. Горизонтальная
// стопка в сайдбаре шириной 4rem либо обрезается, либо ломает раскладку, а
// вертикальная растёт вниз и занимает ту же ширину, что один кружок.
// Порядок наложения задан column-reverse: верхний кружок ложится поверх
// нижнего без z-index, а первое имя списка остаётся первым сверху.
