/**
|
||||
* @suaveplan/react-i18n — Playwright E2E sweep.
|
||||
*
|
||||
* Covers the five user-visible behaviours required by sub-wave 1g:
|
||||
*
|
||||
* 1. Live language switch through 5 locales with localStorage persistence
|
||||
* 2. RTL flip on Arabic — `<html dir="rtl">` + visible reflow
|
||||
* 3. Lazy-namespace Suspense — `<I18nSuspense>` fallback resolves to
|
||||
* translated content
|
||||
* 4. Missing-key overlay (dev mode) — capped at 50 entries with
|
||||
* `aria-live="polite"`
|
||||
* 5. SSR hydration round-trip — server-rendered HTML hydrates without
|
||||
* a React warning AND without a flash of untranslated content
|
||||
*
|
||||
* Per `CLAUDE.md` "Web App & Page Verification": every scenario also
|
||||
* asserts (a) zero console errors, (b) zero failed network requests
|
||||
* (4xx/5xx), (c) the rendered DOM contains the expected content (not
|
||||
* merely a 200 response).
