Summary

• Reorder the embedded console around troubleshooting, offline readiness, native client setup, repository configuration, artifact inspection, and operations.
• Show a standalone sign-in page until credentials are verified. Display invalid credentials inline and preserve native package-client Basic challenges.
• Add an exact-coordinate inventory check for Maven, npm, and Cargo, with clear limits on what catalog presence proves.
• Replace repository creation and token revocation overlays with inline panels.
• Update the README and rebuild the embedded assets.

Verification

• npm --prefix console run build
• cargo check -p teaql-registry --offline
• cargo fmt -p teaql-registry -- --check
• Browser smoke test with a mock REST API: signed-out page, rejected credentials without browser dialog, package diagnostics, offline inventory, client setup, inline repository form, sign-out, and desktop/mobile layouts.
