多分、テスト中に日付が変わると発生する。

Start with e2e-tests/test/admin/total/total.test.ts around lines 133-137 and review the linked Actions failure. Run the affected Chromium test while checking the suspected date transition during execution. Done means the period aggregation check reliably finds #total-products when the test crosses midnight.
