Description

A review of _language-pt-BR.yml by a native Brazilian Portuguese speaker. Most of the file was copied from _language-pt.yml, so a few mistranslations and European Portuguese forms reached pt-BR documents. _language-pt.yml is left unchanged.

Mistranslations and grammar:

key	before	after	why
environment-proof-title	Comprovação	Demonstração	the mathematical term; matches Pandoc's pt-BR translations and babel
copy-button-tooltip-success	Copiada	Copiado!	agreement with "código"; keeps the ! of the English string
toggle-navigation	Alternar de navegação	Alternar navegação	stray preposition
listing-page-field-subtitle	Legenda	Subtítulo	"legenda" means caption
listing-page-order-by-number-asc	Baixo para alto	Crescente	pairs with "Decrescente"
listing-page-order-by-date-desc	O mais novo	Mais recente	pairs with "Mais antigo"
listing-page-field-filemodified	Modificada	Modificado	agreement with "arquivo"
listing-page-minutes-compact	{0}Min	{0} min	missing space, capital M

Brazilian usage:

key	before	after	why
toc-title-document	Índice	Sumário	in Brazil "índice" is the back-of-book index; "sumário" is the table of contents (ABNT NBR 6027, Pandoc's pt-BR Contents)
scrollable-code-label	Código deslocável	Código rolável	Brazilian Portuguese says "rolar" for scrolling; these were marked needs review
scrollable-output-label	Saída deslocável	Saída rolável	same
code-tools-view-source, repo-action-links-source	Ver o código fonte	Ver código-fonte	"código-fonte" is hyphenated
code-tools-source-code	Código fonte	Código-fonte	same
back-to-top	De volta ao topo	Voltar ao topo	more natural
toggle-reader-mode	Alternar modo de leitor	Alternar modo de leitura	"reading mode"
section-title-copyright	Direito autoral	Direitos autorais	usual form in Brazil

Missing key (#14822): link-external-newwindow-label → "(abre em uma nova aba)".

The toc-title-document change is the most visible one, since it renames the table of contents of every lang: pt-BR document. I can drop it from this PR if you prefer.

I rendered an HTML test document with lang: pt-BR and this file as language: and checked that "Sumário", "Demonstração" and "Copiado!" appear in the output.

Obrigado! Sou brasileiro e nunca tinha olhado o nosso pt-BR com cuidado 😬!

(For the non-portuguese speakers: these changes are all good. Let's take them.)

Thanks for the careful review of the file, LGTM. I'll move the changelog entry to the 1.12 file and update the branch with main on our side, so no need to push anything meanwhile.
