# Install and place "aspect-005" (Cinematic Banner) 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/aspect-005.json

Registry item: https://vibeui.ru/r/aspect-005.json
Installs to: components/vibeui/aspect-005.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 21:9 band that becomes 4:3 on a phone: at 360 pixels the cinematic ratio collapses into a 154-pixel slot.

A wide 21:9 band with a heading, description and button on the left. In a narrow column it switches itself to 4:3, because the cinematic ratio degenerates into a slot on a phone. Zero dependencies, one file, its own palette, no client JS.

## 3. How to use it
import { Aspect005 } from "@/components/vibeui/aspect-005"

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-aspect-005-* palette — do not swap it for your theme tokens
- the ratio switch in a narrow column: 21:9 on a phone leaves a band a line and a half tall
- the layout on the inner frame: a container query does not apply to the container itself
- the cqi-based type and padding — measured against the band, not the window
- the text width limit: a line spanning the whole banner does not read
- the text contrast: a gradient sits beneath it, not a flat fill

## 6. You may change
- the title and description copy
- actionLabel and actionHref — the band's action
- the accent through the accent prop — the glow and the button
- the photo: put an <img> inside the frame and it sits under the text

## 7. Rules
- The band expects the full page width. In a 20rem column it becomes an ordinary card — that is fine.
- Do not add a second button: a banner has one action, otherwise it stops being a banner.
- A photo inside needs an alt — or aria-hidden if it is purely decorative.
- 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/aspect-005.json

https://vibeui.ru/r/aspect-005.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-aspect-005-*. Соотношение и вся раскладка живут на внутренней рамке, а не на корне: корень объявлен контейнером, а контейнерный запрос применяется только к потомкам. От 30rem собственной ширины пропорция переключается с 21:9 на 4:3. Кегль и отступы считаются в cqi.

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 Aspect005Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "title" | "children"
> & {
  title?: string
  description?: string
  actionLabel?: string
  actionHref?: string
  accent?: string
}

// Идея компонента: широкая полоса 21:9 — киношная пропорция для баннера во
// всю ширину страницы. Такая полоса не должна становиться высокой на телефоне,
// поэтому на узкой ширине соотношение переключается на 4:3 через container:
// 21:9 в 360 пикселях превратилось бы в щель высотой 154 пикселя.
