📄 Description

Summary

How it works

The existing lang="en" is kept as a sensible default for first-time visitors. An inline <script> in <head> (placed right after <meta charset> so it runs before any content is parsed) reads localStorage.locale — the same key used by the i18n system — and updates document.documentElement.lang immediately. This ensures the browser sees the correct language attribute before it can offer to translate.

The existing initI18n() and changeLanguage() functions in src/lib/i18n/index.ts already set document.documentElement.lang at runtime, so this change is fully consistent with the current approach — it just moves the initial sync earlier to prevent the flash of wrong lang attribute.

Test plan

  • Set UI language to a non-English locale (e.g., Chinese, French)
  • Reload the page
  • Verify the browser does NOT show a translation prompt
  • Verify document.documentElement.lang matches the selected locale
  • With a fresh browser (no localStorage), verify it defaults to lang="en"
