Every Lotus-added feature hard-codes its user-facing strings ("Set Status", "Soundboard", "No Decoration", every shortcut description, every toast/label) as plain JSX text rather than
t('key'). Because the app auto-detects and applies the browser's language (LanguageDetector), a user with a German (or any non-English) browser locale gets a genuinely mixed-language UI: the handful of upstream strings that still route throughen.json/de.jsontranslate, while all Lotus surfaces — which are a large fraction of the app's newer, most-visible chrome (presence, calls, soundboard, decorations, seasonal settings, keyboard shortcuts help) — stay in English unconditionally. This is a single systemic gap rather than N per-string findings.How to trigger
Set the browser's language to
de(or add anotherpublic/locales/<lng>.json), open the app — core translated strings switch language while every Lotus feature panel does not.Suggested fix
Either explicitly scope Lotus Chat to English-only (drop
i18next-browser-languagedetector/remove the now-misleading partialde.jsoncoverage so the experience is consistently English), or route new Lotus strings through the sameuseTranslation()/public/localespipeline used by the 11 already-localized files.Filed from the September 2026 client audit (branch
