Create an internal admin dashboard that lets engineering managers control repository access across our GitHub organization. Build it as a single-page app (Vue.js is fine) that uses GitHub APIs to list repos and manage permissions. Managers should be able to: browse all org repositories in a dense table with search and sort; add or remove collaborators; change permission levels (read, write, admin) in bulk for a selected repo or project; and review access/audit activity for a chosen repository. Prioritize utility over visual polish—fast filtering, clear bulk actions, and an audit trail view.
