// Phase 4 closure (FE-M3): OnboardingWizard mega-page split.
//
// Pre-Phase-4 this file was 1043 LOC containing:
//   • 4 step component definitions (Issuer / Agent / Certificate / Complete)
//   • 2 inline modal helpers (CreateTeamModalInline, CreateOwnerModalInline)
//   • 3 layout helpers (CodeBlock, StepIndicator, WizardFooter)
//   • The shell + state + step transitions
// — all in a single file that took ~30s to navigate end-to-end in the
// editor and hit the eslint per-file-LOC ceiling.
//
// Post-Phase-4 this file is just the shell + state + step transitions
// (~67 LOC). Each step now lives in src/pages/onboarding/ as its own
// file, importable in isolation:
//
//   • types.ts          — WizardStep type + STEPS list
//   • StepShell.tsx     — shared CodeBlock + StepIndicator + WizardFooter
//   • IssuerStep.tsx    — Step 1
//   • AgentStep.tsx     — Step 2
//   • CertificateStep.tsx — Step 3 (owns its inline team/owner modals)
//   • CompleteStep.tsx  — Step 4
//
// Behavior preserved byte-equivalent — no logic change, just a
// directory reshape. DashboardPage's lazy(() => import('./OnboardingWizard'))
// import path is unchanged because this file still exists at the same
// location and still has a default export with the same prop shape.
