locales

Canonical platform-resource locale tags: 2–3 letter language with optional script, region, and variants. General BCP-47 extensions/private-use tags do not map consistently across Android/Xcode and are rejected. Legacy Android qualifiers are accepted and normalized. Defaults to discovery of exact locale-only resource directories (values-en, values-pt-rBR, or values-b+sr+Latn) when a shared project/directory can be resolved. Configuration accepts at most 1,000 entries, each at most 255 characters, before canonicalization.
