/**
|
|
* v1.7.0 W6 — unified dashboard first-paint snapshot hook.
|
|
*
|
|
* One client cell against `GET /api/dashboard/snapshot` that hydrates
|
|
* every above-the-fold tile, replacing the legacy four-cell waterfall
|
|
* (slim analytics + thick analytics + mood + widget layout). Three
|
|
* properties matter:
|
|
*
|
|
* - It is NOT gated on `isAuthenticated`. The server `requireAuth()`
|
|
* is the real gate (401 on a missing cookie); on the dashboard
|
|
* route the cookie is always present because `src/proxy.ts` has
|
|
* already passed the auth / onboarding redirect. Firing un-gated
|
|
* removes the `/api/auth/me` round-trip from the cold critical path
|
|
* (R-firstpaint §1a — the single biggest first-byte win).
|
|
* - `staleTime: 60_000` + `refetchOnMount: false` +
|
|
* `refetchOnWindowFocus: false` mirror `DASHBOARD_QUERY_OPTS` so a
|
|
* return-to-dashboard within a minute is a free cache hit.
|
|
* - `refetchInterval: 120_000` + `refetchIntervalInBackground: false`
|
|
* keep an open dashboard live: an idle tab polls the snapshot every
|
|
* two minutes so freshly-synced Withings / HealthKit readings appear
|
|
* without a manual reload. The poll hits the warm 60 s server cache
|
|
* cheaply and only triggers a sub-second rollup rebuild when the
|
|
* underlying data actually changed — never the LLM surfaces, which
|
|
* stay daily / pre-generated. The interval pauses while the tab is
|
|
* backgrounded.
|
|
* - The queryKey is the centralised factory entry
|
|
* `queryKeys.dashboardSnapshot()`.
