MR: Pending <!-- NOTE: For context on MR heading, see: https://handbook.gitlab.com/handbook/engineering/devops/dev/create/remote-development/index.html#relationship-of-issues-to-mrs --> ## Description As part of our [new designs for Workspaces](https://gitlab.com/groups/gitlab-org/-/epics/18674), we need to improve the existing header section (https://gitlab.com/gitlab-org/gitlab/-/issues/566544+) so that users can quickly identify the workspace, its current status, and associated repository information. ## Visual Changes ![image](/uploads/25f64061cce79ede37ed1c1b091b7440/image.png) ## Acceptance criteria - [ ] Display workspace description or name prominently in the header - [ ] Add coloured status indicator dot next to workspace name - [ ] Show repository path (e.g., "GitLab.org/gitlab-ui") with clickable link to repository - [ ] Display branch information with change counts and commits behind - [ ] Branch information is clickable and links to the branch view ## TODO: Implementation plan - Implement workspace title display using workspace name or description - Add status indicator component using existing enhanced status indicator patterns - Display repository information with proper link generation to GitLab repository - Implement branch information display using data from [branch & local files information](https://gitlab.com/gitlab-org/gitlab/-/issues/565017) - Add proper click handlers for repository and branch navigation - Style header section following GitLab design system header patterns ## Technical Notes - **Status Indicator:** Reuse enhanced status indicator component with coloured dots from previous workspace card work (See: https://gitlab.com/gitlab-org/gitlab/-/issues/562357+s) - **Branch Data:** Uses branch and local changes information implemented in https://gitlab.com/gitlab-org/gitlab/-/issues/563085+s & https://gitlab.com/gitlab-org/gitlab/-/issues/565017+s <!-- NOTE: Feel free to expand with more sections and headers as needed --> <!-- DO NOT TOUCH BELOW -->
