 *
 * Two dev-environment flakes are tolerated here so the *behaviour under test*
 * (create → detail page) is what's exercised, not infrastructure noise:
 *
 *  1. The local Supabase gateway (Kong) intermittently returns 500
 *     "An invalid response was received from the upstream server" / "fetch
 *     failed" when its PostgREST upstream is momentarily unavailable — observed
 *     on ~30% of create calls, and far more often while the modal's per-project
 *     fetch burst is hammering Supabase concurrently. We wait for that burst to
 *     settle before submitting, and retry the POST on transient 5xx. A genuinely
 *     broken create flow fails *every* attempt, so regressions are still caught.
 *  2. `next dev` compiles the dynamic /tabular-reviews/[id] route on first
 *     navigation (15-30s cold); under that latency the dev server can drop the
 *     in-flight client navigation, so we fall back to an explicit goto.
 *
 * @param onFirstOpen optional assertion run against the modal on the first open
 *        (used by Test 2 to verify the workflow-template default renders).
