/**
 * Tier-4 E2E — deterministic UI-presence journeys for the Insurance Advisor
 * frontend. Run via the playwright-skill runner:
 *   node /Users/rohitsar/.claude/skills/playwright-skill/run.js \
 *     audit/e2e/insurancebot_e2e.js
 *
 * The runner injects Playwright (resolved from the skill's node_modules) and
 * passes this file through verbatim because it already has `require(` + an
 * async IIFE. Every journey resolves to a boolean; everything is wrapped so a
 * single `RJSON {...}` line is ALWAYS printed to stdout — even on a hard
 * failure — so the Python check can parse it (no RJSON => WARN/infra, never a
 * silent FAIL). These are presence/no-error checks only: NO multi-turn LLM
 * chat (that is flaky/slow and not a deterministic UI signal).
