Specification
https://www.w3.org/TR/appmanifest/#x_localized-members

Summary
Supports localization of manifest members so apps can adapt their names, descriptions, icons, and shortcuts to the user’s language and region. Developers provide localized values in the web app manifest, and the browser selects the appropriate localizations based on the user’s language settings, introducing language support across different markets.

Blink component
Blink>AppManifest

Web Feature ID
Missing feature

Motivation
PWAs are used worldwide, but the web app manifest only supports a single language. This limits developers who want their apps to feel native and accessible to users across different regions.
