Module load cost
Counted with a module.registerHooks load hook, compile cache disabled. Counts every JS module actually evaluated on that code path (built-ins excluded, native addons excluded).

Install footprint and published tarball
Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.

📚 Description
In the dev TUI you can only copy one row at a time, so there is no quick way to hand the errors to an agent or to paste the project info in an issue.
shift-ynow copies everything the open view is showing, with its filters and search applied. In the logs,ethenYgives you all the errors. It keeps the newest entries when there is too much to paste (60k chars) and the notice says how many were copied. It works the same in the requests, request trace and routes views since it lives inScreenOverlay.In the info view,
Ycopies the markdown tablenuxt infoproduces instead of the rows, which are URLs, uptime and a QR code. For that the collection part of theinfocommand moved into an exportedcollectProjectInfo(cwd), the diff ininfo.tsis a pure move and reads best with whitespace hidden. It's imported on demand since it evaluates the project's config.The copy hints were also inconsistent: logs and routes said
enter, requests saidysinceenteropens the trace there, and info said nothing. Every view now showsy copyandY copy all.enterstill copies where it did.I checked it in a real terminal against the playground on macOS, both the logs and the info table land on the clipboard.
