/**
 * Smoke tests for the unified rSocials campaign flow UX.
 *
 * Covers the integration points from the recent refactor:
 *   1. /campaigns dashboard lists flows + routes to /campaign-flow?id=X
 *   2. Brief canvas node replaces the old slide-out — generate + preview banner
 *   3. Markdown import modal adds post nodes wired to a platform
 *   4. Wizard success page links into /campaign-flow?id=<flowId>
 *
 * Set BASE_URL=http://localhost:3000 for local runs. The /api/campaign/flow/from-brief
 * and /api/campaign/wizard/:id/content endpoints require GEMINI_API_KEY — tests that
 * depend on AI are skipped automatically when the API returns 503.
