/**
|
|
* Generates ios/LichessWidgets/Localizable.xcstrings from the app's ARB translation files.
|
|
*
|
|
* Run from the repo root:
|
|
* node scripts/gen-widget-strings.mjs
|
|
*
|
|
* The output is a String Catalog (Xcode 15+) containing all widget UI strings.
|
|
* Xcode picks it up automatically via the fileSystemSynchronizedRootGroup.
|
|
*
|
|
* To add a new string:
|
|
* 1. Add the ARB key to WIDGET_KEYS below with its default English value.
|
|
* 2. Re-run this script.
