Localizations

Muxy is in English. A language pack is an extension that adds app languages. Users find packs with Settings → Appearance → Browse language extensions… and pick one under App language. Text a pack doesn't translate stays in English.

Field	Notes
`id`	Unique within the extension.

Bundle layout

localization/
  German.bundle/
    Info.plist
    de.lproj/
      Localizable.strings
      Localizable.stringsdict    (optional, for plurals)

Localizable.strings maps English text to translations:

"Apply Layout" = "Layout anwenden";
"Tab %lld" = "Tab %lld";

The keys are the app's English strings. The full list is crates/muxy-app/localization/en.lproj/Localizable.strings.
Placeholders such as %@ and %lld must match the key's, in type and position. Positional forms like %1$@ may reorder them. A bundle with a mismatch is rejected.
Each file can be up to 4 MiB. The bundle must not contain executable code.
Load errors go to the pack's log in Settings → Extensions.

Muxy 2 uses new English strings, so packs made for 1.x load but translate only part of the app.
