 Merged PR #333 as `b04684f2432aa474cb84874aa26aa08a5f4c5ab7` implements the canonical contract in `docs/admin-maintenance.md`: a separately authorized maintenance surface that inventories Classroom and Standalone collaboration data, derives idle/expired state from server timestamps + recent presence, previews destructive cleanup, and safely purges selected or bulk stale records. Administration is not a fourth Intake experience role. It also becomes the intentional recovery path for rotating/reissuing Instructor authority after #328 removes the public Instructor access-code form.

-Draft PR #334 replaces implicit role restoration with a startup hub that offers **Continue where you left off** when valid saved/resumable context exists, plus **Work independently**, **Join a class**, **Run a class**, and secondary **Administration / Maintenance** entry. Cached Intake, Student resume, and Instructor resume are presented as separate explicit choices rather than silently selecting a role.
