/**
 * Structure tests for the 3-step Pool Wizard (Phase C1).
 *
 * These assertions intentionally read the source files as text to verify:
 *   - PoolWizard.tsx contains all 3 wizard steps
 *   - The PATCH body includes the `exclusive` flag
 *   - quotaModelName is imported for the preview
 *   - QuotaSharePageClient mounts <PoolWizard
 *
 * Node native test runner (no JSdom needed — pure source analysis).
