// Structure guard for the collapsed Tasks page (issue #461). The Tasks page is ONE `user_tasks`
// dataGrid (`filter: []`, `orderBy updated_at desc`) with `kind_label` as a "Type" column, completing
// each row via its ENGINE-declared form (nano-ide#457's `detail.engineForm`) — not seven
// `element_id`-allowlisted grids each with a hand-authored `detail.form` that duplicates a deployed
// `.form` resource AND leaves dynamic-id delivery-graph tasks (counted by the `filter: []` badge)
// rendered by no grid. This test pins that end-state so the anti-pattern can't creep back:
//   • exactly one `dataGrid`, over `user_tasks`, unfiltered, recency-ordered → badge ≡ list;
//   • a "Type" column bound to `kind_label`;
//   • an engine-form detail (`form_key` / `user_task_key`), and NO page-local `detail.form`.
