feedback5: Japanese, Korean and Traditional Chinese ship — the official game texts of the JP / KR / TW clients (data/i18n/ja.json 96.5 %, ko.json 97.4 %, zh-TW.json 91.1 % of 22 114 texts, built with build-i18n --lang from ArknightsAssets/ArknightsGamedata) and minimal UI packs public/i18n/ja.json, ko.json, zh-TW.json (a _meta manifest, no UI strings yet): ja / ko fall back to the English UI, zh-TW to the Simplified Chinese UI (no fallback; numbers in 萬 / 億); the owner's decision of 2026-10-07; UI translations welcome from the community; golden: unchanged (client text only)

- The packs: _meta = type lang, the code, its own and English name (日本語 / Japanese, 한국어 / Korean, 繁體中文 /
  Traditional Chinese), version 0.2.0, app >=0.2.0, authors, credits (the official client data, © Hypergryph (/ Yostar
  for JP and KR), via ArknightsAssets/ArknightsGamedata), fallback ["en"] for ja / ko and [] for zh-TW; formatted as
  `node tools/i18n.mjs template` writes them, so a translator runs it on the shipped file and keeps the manifest.
- Built offline from the tables W5AD downloaded and checked today (jp / kr 51.10.0, tw 51.2.0; copied into
  .cache/gamedata-<code>): coverage as W5AD measured; `build-i18n --lang <code> --check` up to date for en, ja, ko,
  zh-TW. `node tools/i18n.mjs check --all --strict`: 0 errors (en complete; ja / ko / zh-TW 0 of 1022 msgids, fallback).
  `node tools/packs.mjs list` lists the four packs with their game texts; `tools/package.mjs --dry-run --list` ships
  data/i18n and public/i18n of all four and the generated packs/index.json.
- With five languages the menu is a list (ui/lang.js SEGMENTED_MAX 4, W5AD's rule): test/ui/i18n.e2e.test.js reads and
  picks either form, expects the shipped languages, and checks each new pack in the browser (its official game text,
  the fallback UI, <html lang>) — SP_E2E=1: 3 / 3; the title page of the five devices (devices.e2e "title page") still
  fits: 5 / 5.
- Docs: docs/I18N.md (intro, §2, §5 "Shipped packs" with the call for UI translations), docs/PLAYING.md (语言),
  DESIGN §25.20 and the §25 intro's decisions of 2026-10-07.

Gate: non-browser suites 5024 / 5024 (test/i18n*, test/package, client-static 358 / 358), npm run golden ok,
test/golden.test.js 9 / 9, lint 0 errors, check:imports ok, typecheck ok.
