What autoglot preserves

@@ file attributes and @message resource metadata
Simple placeholders such as {userName}
ICU plural, select, date, time, and number expressions
Existing target-only messages and metadata when files are updated

Set the GitHub action paths input to your Flutter l10n directory. autoglot discovers English templates such as app_en.arb and writes Flutter locale suffixes such as app_pt_BR.arb and app_zh_Hans.arb.
