// Browser check of the language switch (puppeteer-core + system Chrome; opt-in: SP_E2E=1, ~20 s):

// SP_E2E=1 node --test test/ui/i18n.e2e.test.js

|
|
// The title screen opens in Chinese; 中文 | English → English in place (no reload): the title, the start button, the
|
|
// connection line, <html lang>, the tab title; the choice is kept across a reload (localStorage sp.pref.lang) and the
|
|
// game-data overlay (data/i18n/en.json) is applied; `?lang=zh` switches back and leaves the address bar. Language packs
|
|
// (docs/I18N.md "Adding a language", docs/PACKS.md): a pack file dropped into public/i18n/ and a pack folder dropped
|
|
// into packs/ while the server runs show in the menu and switch, with English filling what they lack; a removed pack
|
|
// sends a stored choice back to Chinese. The shipped Japanese, Korean and Traditional Chinese packs (the owner's decisions of
|
|
// 2026-10-07) switch to their official game texts and their own UI strings (what a pack lacks shows its fallback: English
|
|
// for ja / ko, the Simplified Chinese for zh-TW); a pack marked `machineTranslated` says so in 设置 (none in Chinese).
|
|
// With more than four languages the menu is a list (ui/lang.js SEGMENTED_MAX): the helpers read and pick either form.
|
|
// No console / page / request errors. docs/I18N.md.
