/**
 * v1.4.15 phase-A3 fix #3 — onboarding card flicker on dashboard load.
 *
 * The previous version of `<GettingStartedChecklist>` rendered against a
 * default-true `shouldShowChecklist` decision while `measurementCount`
 * was still 0 (analytics query in flight). For a fully-onboarded user
 * (`onboardingCompletedAt != null` AND `measurementCount >= 5`), the
 * card briefly flashed before tanstack-query wrote the real value and
 * `show` flipped to false on the next render.
 *
 * This spec asserts the card is NEVER visible — at any sampled instant
 * during page load — when both:
 *   - the auth user has `onboardingCompletedAt != null`, AND
 *   - `/api/analytics` returns ≥5 measurements.
 *
 * We slow `/api/analytics` deliberately so any "render-before-data"
 * race condition would be fully visible to a Playwright `isVisible()`
 * probe; with the fix in place, the card stays unmounted because the
 * component refuses to render until `analyticsQuery.data !== undefined`.
