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.
