/**
 * Deterministic smoke tests for the new-work interactive flow.
 *
 * Covers the parts a user actually touches: the serve-question decision page
 * (pick, re-roll + steer + re-deal, canon, tab close) driven through a real
 * browser by the scripted user bot, plus the offline fake image generator.
 * No LLM calls; a real Chromium via Playwright supplies full page fidelity
 * (heartbeats, re-roll reload, tab close). Kept OUT of `bun run test` like
 * live-e2e; run it with `bun run test:new-work-e2e`.
 *
 * The concept-seed direction roll (challengers, ASSIGNED INDEX, the no
 * PRODUCT.md gate) is already covered by tests/concept-seed.test.mjs and is
 * not repeated here.
 *
 * One-time setup:  npx playwright install chromium
