+# Brazilian Portuguese (`pt`)
+
+Catalog: `src/i18n/locales/pt.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+Translation source: abiyeenzo (#909).
+
+## Style
+
+- Brazilian Portuguese (pt-BR): câmera, tela, compartilhar, arquivo, baixar, ônibus, metrô. Every `pt` tag, `pt-PT` included, gets this catalog, so avoid slang and regionalisms.
+- Address the user with «você» imperatives: «Clique no mapa», «Ative o CCTV», «Tente novamente». Tooltips that name an action use the infinitive: «Expandir painel», «Redefinir a câmera».
+- Sentence case, not Title Case: "Live Flights" → «Voos ao vivo». UPPERCASE English stays UPPERCASE: «AO VIVO», «SEM DADOS».
+- Quotes inside Portuguese text are straight double quotes: «Excluir o plano "{shot}"?». A sentence that names a panel quotes it: «o painel "Configurações de provedores"» as the subject, so the verb agrees, and «adicione em "Configurações de provedores"» after a preposition.
+- A dash between clauses is a spaced em dash « — », even where the English runs it in.
+- A date or time after a participle takes a preposition: «emitido em {time}», «válida para {valid}», «Posição em {time}», «onde estava em {time}». Use «em», not «às», wherever {time} can include a date.
+- A count in a string with no plural form (no `tn()`) goes after a colon, so it reads right for 1: «sincronizando feeds de cidades: {count}...», «CÂMERAS EM ESPERA: {count}».
+- A placeholder that holds a layer or tool name of unknown gender and number gets a noun to agree with: «{label}: camada ativada», «A ferramenta "{owner}" está usando o ponteiro — feche-a primeiro».
+- Short labels, chips and HUD readouts stay short. A standard abbreviation with a period beats a wrapped line: ANT., PRÓX., DESLIG., EXCL., INCL., ALT., VEL., câm.
+- The HUD codes HDG, BRG, CRS, FOV, DEST, SPD, RANGE, ALT, GS, TRK and V/S stay in English, as in cockpit avionics («ALT {altitude} FT · GS {speed} KT · TRK {track}», «V/S {rate} FT/MIN»), and so does the HUD recording mark REC. Words used in a sentence are translated: heading → «rumo», range → «alcance».
+- Keyboard keys stay in English: Space, Esc, Enter, Tab, Shift, Backspace, H, 1–9 («Segure Space para falar»).
+- Common English tech words used in Brazil stay: feed, stream, snapshot, briefing, dock, layout, bloom, status, app, link, token.
+- Units: km, m, km/h, m/s, kt (knots), ft (feet), h, min, s, always spaced from the number («Terremotos (24 h)», «Missões espaciais (30 d)»; in the layer names the space is a no-break space, U+00A0, so the unit never wraps away from the number); in UPPERCASE text KM, KM/S, KT, FT, MIN, H. "m" is always metres, so minutes are «min» («há 5 min»). MW stays MW. `°` and `%` stay. Decimal comma in written numbers («M4,4»).
+- "ago" goes before the time: «há {count} min», «mais recente há {value}». When a placeholder already holds a localized "ago" text (`{age}`, `{ago}`), do not add «há» again.
+- Money: «US$ {amount} mil / mi / bi» for thousands, millions and billions.
+- Compass points use Leste/Oeste: N, NNE, NE, ENE, L, ESE, SE, SSE, S, SSO, SO, OSO, O, ONO, NO, NNO; hemisphere letters N, S, L, O.
+
+## Plurals
+
+A `tn()` entry needs three forms. `Intl.PluralRules('pt')` follows Brazilian usage:
+
+| Form    | Counts                                 | Example            |
+| ------- | -------------------------------------- | ------------------ |
+| `one`   | 0, 1 and anything below 2: 0, 1, 1.5   | 0 câmera, 1 câmera |
+| `many`  | 1 000 000, 2 000 000… (exact millions) | 1000000 de câmeras |
+| `other` | everything else: 2–999 999, 2.5…       | 3 câmeras          |
+
+The `many` form is the `other` text with «de» after the number: «{count} de câmeras carregadas», «{count} DE CHAVES PENDENTES». A `one` form is also read for 0, so keep it natural with zero («0 arquivo selecionado» is standard Brazilian usage).
