Add pt-BR to the locale list and everything that hangs off it: the client loader, Intl and date-fns mapping, the reply-language footers of the Coach and insights prompts (English body, pt-BR footer, the same path Korean and Dutch take), the citation-coverage normative words, the no-key fallback copy, the AUDIT-C standard-drink line, country labels, period search, CSV yes/no cells and the Telegram bare-word aliases. The locale enums in the extract, managed-profile and record-settings schemas now derive from the locale list instead of repeating it, and the five notification and login-alert routes share one isLocale guard instead of hand-rolled chains, so a later locale is one edit there. A language tag is matched exactly and case-insensitively before its primary subtag, so pt-BR and pt-PT browsers land on the Portuguese bundle rather than English, and AUDIT-C no longer cuts a region tag to two letters. PHQ-9, GAD-7 and WHO-5 are not marked validated for pt-BR: the wording has not been read against the published Brazilian forms, so readers get the English items plus the existing note.
