Portuguese (Brazil), completing Phase 1

781 of 796 strings; the fifteen left are product names, bare URLs and example
addresses. Generated by AI, unreviewed, marked Beta.

This is Brazilian Portuguese specifically, and the tag says so rather than
claiming "Portuguese". It is not a stand-in for European Portuguese: the
vocabulary diverges in exactly the places a mail client lives -- arquivo
against ficheiro, tela against ecrã -- and offering one variety as though it
were the other is worse than offering English, because the reader cannot tell
it was not meant for them. A pt-PT catalogue would be a separate file.

Register is "você", and this is the one place Phase 1 deliberately breaks its
own rule. The other four all took the formal address; Brazilian Portuguese has
no comfortable equivalent. "O senhor" is deferential rather than merely polite
and reads as stiff or sarcastic in software, while "você" is the neutral
default Gmail, Outlook and every Brazilian bank use, carrying none of the
familiarity "du" or "tu" would elsewhere. Following the rule here would have
produced a worse translation by obeying a decision made about other languages.
The rule was always "address the reader the way the language does it", and
these five are what that looks like rather than five copies of one answer.

"Marcador" for label, which is Gmail's word in Brazil: a fourth different
outcome from the same rule about using what the reader will meet elsewhere,
after English, Libellé and Etiqueta.

Phase 1 is complete: de, fr, nl, es, pt-BR, each unreviewed and each marked
Beta until a speaker signs it off. That review is the part nobody has done and
the part that decides whether any of this was worth shipping.
