WIP Limit Board

A board with a per-column card limit: the fill is visible before the move, and an over-limit move is refused out loud instead of being cancelled silently.

# Install and place "kanban-002" (WIP Limit Board) 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/kanban-002.json

Registry item: https://vibeui.ru/r/kanban-002.json
Installs to: components/vibeui/kanban-002.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 board with a per-column card limit: the fill is visible before the move, and an over-limit move is refused out loud instead of being cancelled silently.

A work-in-progress limited board: an occupied-of-limit counter, a fill bar and a spoken refusal when the limit is reached. Zero dependencies, one file.

## 3. How to use it
import { Kanban002 } from "@/components/vibeui/kanban-002"

<Kanban002 columns={[{ name: "Doing", limit: 2 }]} cards={[{ id: "1", title: "Task", column: "Doing" }]} />

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-kanban-002-* palette — do not swap it for your theme tokens
- the arrow buttons: dragging is fundamentally unavailable from a keyboard
- the role=status live region: a silently cancelled move looks like a broken interface
- the counter computed from the cards — a stored number lies after the first move
- the fill bar next to the number: approaching the limit must read without counting
- the column aria-label carrying the card count and the limit

## 6. You may change
- the columns and cards arrays together with the limits
- the onChange handler
- the accent through the accent prop and the warning colour
- the column width

## 7. Rules
- Order inside a column does not change: the move only sets membership.
- The limit is checked for mouse and keyboard alike — both paths go through one function.
- State lives inside the component: persisting it is the caller's job.
- 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/kanban-002.json
https://vibeui.ru/r/kanban-002.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-kanban-002-*. Клиентский: "use client" ради состояния доски. Колонка описана парой имя и лимит; заполнение считается из карточек и показывается числом «3 / 4» и полосой. Функция переноса одна для мыши и клавиатуры: она проверяет лимит и в случае отказа пишет причину в живую область role=status. Мышиный путь — нативный HTML5 drag and drop, клавиатурный — кнопки со стрелками на карточке.

Component source

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

"use client"

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

export type Kanban002Column = {
  name: string
  limit: number
}

export type Kanban002Card = {
  id: string
  title: string
  column: string
}

export type Kanban002Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange"
> & {
  columns?: Kanban002Column[]
  cards?: Kanban002Card[]
  onChange?: (cards: Kanban002Card[]) => void
  accent?: string
}

// Идея компонента: доска с лимитом карточек в колонке. Лимит бесполезен, если о
// нём узнают только постфактум, поэтому колонка показывает «3 / 4» до переноса,
// переполненная подсвечивается предупреждением, а отказ произносится вслух в
// живой области: молча отменённый перенос выглядит как поломка. Перенос мышью
// сделан нативным drag and drop, а кнопки «влево» и «вправо» дают тот же
// результат с клавиатуры — drag с неё недоступен в принципе.
