# Task: Add content production collaboration panel

## Feature

## Goal

Make the content detail page expose the existing production collaboration data that is already loaded by the frontend store: comments, content revisions, linked assets, asset revisions, and workflow activity.

## Scope

- Keep comment creation and resolution available.
- Show content revision history with change summaries.
- Show linked assets and their revisions.
- Add UI for linking a Google Drive asset and adding a new asset revision.
- Show content-scoped notification activity as a read-only production activity feed.

## Likely Files

- `frontend/src/features/content/stores/contentItemDetailStore.js`

## Out Of Scope

- Native file uploads.
- Mention parsing.
- Approval comment visibility rules.
- Reworking content variant persistence.

cd frontend
npm run build
```
