// batch07-stale-click.mjs — click delete on an already-stale preview.
//
// Companion to batch07-stale-preview.mjs, which stages a preview and waits out
// maxPreviewAgeForDelete. This half assumes the wait is already done: it
// re-renders whatever preview the hold is holding and clicks delete on it.
//
// GET /admin/api/gc/status re-renders lastPreview WITHOUT touching
// lastPreviewAt, so displaying an old preview does not reset its age. That is
// what makes this resumable after a failed run, instead of costing another 31
// minutes.
//
// Two things learned the hard way, both encoded below:
//
//   * page.on('dialog') did not reliably intercept the hx-confirm on this page.
//     The unaccepted native dialog then blocks every subsequent evaluate() and
//     innerText(), so the script hangs rather than failing. The confirm is not
//     what is under test, so the attribute is stripped before clicking and no
//     dialog is ever raised.
//
//   * The delete button is not the first "Delete" on the page when a Reconcile
//     button is also rendered, so match the full label.
//
//   node test/e2e/batch07-stale-click.mjs
