/**
* @fileoverview
* Define message file to be used for a given locale. A few aliases are defined below.
*
* Google locale inheritance rules: https://goto.google.com/ccssm
* CLDR language aliases: https://www.unicode.org/cldr/charts/latest/supplemental/aliases.html
* CLDR locale inheritance: https://github.com/unicode-cldr/cldr-core/blob/master/supplemental/parentLocales.json
*
* For Lighthouse bundles that shouldn't include locale data, the recommended pattern
* is to replace the default export of this file with `{}` so that no locale messages
* are included. Strings will work normally through the IcuMessage.formattedDefault
* fallback, and locale messages can be added on demand (e.g. dynamically fetched)
* through `format.registerLocaleData()`.
