* i18n Translation System — E2E Tests
|

*
|
|
* Verifies that:
|
|
* 1. Platform translation API (/platform/i18n/{locale}.json) is requested on load
|
|
* 2. Translated strings render correctly in the UI (no raw keys visible)
|
|
* 3. Offline fallback works when Platform API is unavailable
|
|
* 4. Locale switching re-fetches and updates displayed text
|
|
* 5. Multiple routes render translated content without raw keys
