feedback5 WAD: language packs are the first type of content packs — a language is a file in a language folder (public/i18n/<code>.json, optional data/i18n/<code>.json) or a pack folder (packs/<id>/pack.json); the server lists them live at /packs/index.json (server/packs.js), the menu shows every pack, strings fall back pack → base → declared fallback (English) → Chinese, broken placeholders are skipped, plurals follow Intl.PluralRules (English unchanged), English carries a _meta manifest like any pack; tools: i18n.mjs template / check <code>, packs.mjs list / index, build-i18n --lang ja|ko|zh-TW (the official JP / KR / TW clients); the release zip ships packs/ and a generated packs/index.json; golden unchanged
