# Page `openGraph` replaces the layout's (shallow merge drops images/siteName)

`lint/og-merge-drops-parent` · severity **warn** · category Lint · detected by `void lint` and `void audit`

## Why it matters

Next merges metadata shallowly: when a page sets `openGraph`, the parent's whole `openGraph` object is replaced. Images, `siteName`, `locale` defined in the layout silently disappear from that page's link previews. Same for `alternates` (`types`, `languages`).

## How to fix it

Spread shared fields back in (`openGraph: { ...sharedOpenGraph, title }`) or use file-based `opengraph-image` in the segment.

## Example

```ts
import { sharedOpenGraph } from '@/lib/seo'
export const metadata = { openGraph: { ...sharedOpenGraph, title: 'Pricing', url: '/pricing' } }
```
