/* global React, useState, useEffect */
/* ============================================================
   i18n — bilingual FR/EN runtime.

   Usage:
     const t = useT();
     <h1>{t("habits.title")}</h1>

   For strings that come from data (e.g. user-typed names), DON'T
   translate; use them as-is. Translate ONLY UI chrome strings.

   The lang state lives in the app (Tweaks → "lang"). The shell
   pushes the current lang onto window.__dpmLang and dispatches the
   "dpm-lang-change" event whenever it flips, so any component using
   useT() re-renders on flip.

   Translation keys are dotted; missing keys fall through to the FR
   value, and if that's missing too, return the key itself so
   debugging is easy.
