/**
 * v1.31.0 — Today reacts in place.
 *
 * The milestone's actual moment: new data lands, and the ALREADY-OPEN
 * dashboard starts reading differently on the cadence it already runs. No new
 * poll, no push, no socket — a state change, not a notification.
 *
 * The spec drives that end-to-end against the real read path:
 *
 *   0. give the account a reason to paint a hero at all — one integration
 *      needing a reconnect, which is an ordinary Today for someone whose
 *      readings sync from devices;
 *   1. load the dashboard with last night's sleep still missing, and prove
 *      it reads provisional with the pending note up;
 *   2. land it through the REAL batch endpoint, and the arrival marker the
 *      spine's worker would have written;
 *   3. surface the tab's real visibility-change signal — the browser event
 *      TanStack Query's focus manager consumes for
 *      `refetchOnWindowFocus: "always"` (alongside the 120 s foreground poll);
 *      using that existing trigger keeps the test inside the real cadence
 *      while staying well under the poll interval;
 *   4. assert the phase flipped and the pending note cleared — in place, no
 *      reload.
 *
 * The hero used to carry a "just in" chip here; it is gone, because under a
 * number "just in" never said what had arrived. What the milestone was
 * always about survives it: the open page reads differently on its own
 * cadence.
 *
 * Step 0 is what the chip's removal exposed rather than caused. The arrival
 * was the only thing keeping the hero on screen for this bare fixture
 * account, so the spec was watching the day flip on a hero its own subject
 * was propping up — and on whatever data a sibling spec happened to leave
 * behind. It now establishes its own precondition, so the hero is there for
 * a reason a reader would recognise and the run order cannot decide the
 * outcome. `today-hero-just-in.test.tsx` pins the same composition at the
 * component, since this file cannot be run without a built app.
 *
 * The marker is seeded directly rather than waited for from pg-boss: whether
 * the queue drains inside the e2e web server is the SPINE's contract and has
 * its own tests. What this spec owns is everything downstream of a marker
 * existing — the read path, the DTO, and the surface.
 *
 * Assertions anchor on `data-slot` / `data-phase`, never on visible text:
 * responsive `sm:hidden` classes have broken `getByText` in this repo before.

    // dashboard snapshot, which is an SWR cell in the analytics bucket
    // (60 s fresh, one HOUR of stale-serve), so the desktop run's
    // "sleep is in" snapshot outlived the rows it was built from and the
    // mobile run read `final` from cache against an empty table.
    //
    // `bulk-delete` specifically: it hard-evicts that bucket
    // (`invalidateUserMeasurements(userId, { evict: true })`, pinned by its
    // own route test), tombstones the rows the way the management list
    // does, and recomputes the rollup buckets the snapshot reads through.
    // The delete-by-external-id route would have been the closer fit for
    // how this spec names its rows, but it invalidates WITHOUT `evict` —
    // a marked-stale cell is served immediately while it revalidates, so
    // the next read would still have been the stale `final` one.

    // Ids come from SQL rather than from `GET /api/measurements`: that
    // list collapses overlapping sources to one canonical row per day, so
    // it can hide a row that is still in the table and still counts.
