/* ---------- Languages ----------
HOW TO ADD A LANGUAGE (e.g. French):
1. Copy the whole "en" entry below (name + strings).
2. Paste it as a new entry, e.g. fr: { name:"Fran\u00e7ais", strings:{ ... } },
3. Translate every value, keeping "{n}", "{sum}" and "{target}" placeholders.
The header language menu is built from LOCALES automatically, so no
other code changes are needed. Missing keys fall back to English.
