Question being tested: which shared page structure should replace the Workspace and Pi popups while bringing Workspace, Evidence, Memory, Database and Pi into one responsive administration family?

Run it from frontend/:

npm run prototype:administration-pages

Then open http://127.0.0.1:5174/?thoth_route=administration/workspace&variant=A.

The three variants are:

A, Administration Workbench: a dense index beside a persistent detail surface.
B, Administration Inspector: a reading-first page with an explicit configuration form and provenance column.
C, Operations Deck: a status-led page with a full-width inventory and an activity console.

All variants simulate the same Workspace data, the same five administration links, and the same read-only form interactions. Use the floating switcher or ?variant=A|B|C to compare them. The prototype is intentionally isolated from production routes and is expected to be deleted after the winning structure is captured in the implementation specification.
