Add the key to both the pt and en dictionaries in webapp/src/strings.js, then read it via useStrings() in the component. The i18n test fails if a key exists in only one dict, so a missing translation becomes a red test.

Use the resolveLocale() pure function: if the BCP-47 primary subtag before the first hyphen equals 'pt', return 'pt'; any other language returns 'en'. A saved localStorage choice overrides detection, and the rule is duplicated in the pre-paint script in index.html.

No. The webapp is a fully static site that reads a committed JSON snapshot (meta, articles, contents) from webapp/public/data. It has no backend and no env vars; BYOK API keys live in localStorage.

Two LanguageToggle instances mount at once (topbar and tutorial card), and Motion layoutId must be unique across the tree. Pass a distinct layoutId prop such as 'lang-pill-tut' to the tutorial copy so the shared-layout pill does not teleport.

The onboarding tutorial modal intercepts all pointer events on first visit. Set localStorage 'nc-tutorial-seen' to '1' via addInitScript before page.goto, otherwise clicks time out against the overlay.

Do not use it for the AI search rubric, prompts, or the export snapshot contract — those belong to the searching-the-corpus skill. This skill covers only UI chrome: strings, theming, tutorial, toggle, and React components.
