 - The expanded `CONTEXT` view offers mutually exclusive `CONTACTS` and `SPACE MISSIONS` modes. Selecting `CONTACTS` enables the context-owned Flights, Military Flights, AIS Vessels, and Mapped Installations dependencies only when they are not already user-enabled; selecting `SPACE MISSIONS` enables the recent-launch layer and its Satellite dependency. `CONTACTS` cycles the nearest supported contact of whatever type is selected. Satellites are deliberately excluded from those Awareness cohorts and keep their own tracking UX. Selecting the active mode again returns to the neutral chooser and releases only mode-owned dependencies.
 - If a civilian or military aircraft is already tracked when `CONTACTS` becomes operational, that source-owned track is adopted as the Context subject before nearest-contact autofocus. Context rechecks the tracker after its dependencies settle, so a newer selection wins, while an explicit clear during activation prevents fallback from silently selecting a replacement. Cockpit entry remains unavailable until that Context transaction has settled, so its camera takeover cannot clear Cesium tracking before adoption. Adoption does not recreate tracking or transfer camera ownership; it initializes the normal 250 km ring, history, proximity results, and Cockpit Previous/Next state for the original aircraft.
 - `SEARCH NEARBY SITES` retains the bounded OSM results and makes one user-initiated, view-biased Google Maps Places text search for “military installation.” Google results are source-stamped, deduplicated against OSM by rounded location/name, and remain mapped context rather than operational claims. If Places is unavailable or the API is not enabled for the supplied key, OSM context remains available. A view across the antimeridian is searched around its own centre, with a radius from its real width.
+- The Context header holds only its title and collapse control. It no longer carries a Radio shortcut or a compact Radio player: Radio is the `RADIO` section inside the panel, with its own disclosure and the single `ENABLE` power control. Cockpit keeps its own compact Radio utility.
+- Context is set for reading in every theme: mode, standby and action labels are 10 px, and the panel draws no glow halo. Outside Cyber, the two modes form one segmented control, the standby guidance is plain left-aligned text rather than a dashed placeholder, and the expanded panel's section titles use `--text-secondary`. Cyber keeps its separately framed mode buttons, its red panel titles, and in layout-focus a framed, centred standby card over its radar art.
 - The expanded desktop header omits the redundant `ON` label; the active mode button carries state. Expanded Contact results also omit the duplicate `GLOBAL CONTEXT` / `CONTEXT ONLY` status row and begin with the selected subject and its 250 km scope. Global Context does not fabricate a selected-entity model preview: the provisional hand-authored aircraft wireframe was removed because it was not geometry extracted from the selected entity's actual asset.
 - Dependency ownership is reversible: disabling Global Context releases only dependencies it enabled, while user-enabled layers remain on. This also removes the Military-layer suppression handoff when Global Context owned Military, allowing an already-enabled civilian Flights layer to resume its normal mixed rendering. If OpenSky is unavailable and has no last-good cache, Flights requests a capped 250 nm adsb.lol point snapshot around the current view anchor and labels that provenance explicitly; it never relabels military-feed rows as civilian data. If both inputs fail, Flights remains `UNKNOWN`.
 - Space Missions is replay-isolated: Rocket Launches and Satellites are the only Data Layers permitted while the mode is active. Direct UI and voice entry capture the same pre-entry snapshot; internal dependency and restoration enables do not create a user-owned Context session. Entry waits for incompatible layers to shut down, direct incompatible enables are blocked before lifecycle work, and the entry gate remains active through the complete Rocket Launches enable. A newer same-target ON request takes ownership of the pending entry without releasing its isolation snapshot, including when it arrives while the prior request is awaiting the adoption guard. A caller abort, resource cancellation, newer OFF, or layer teardown waits for exact manager settlement and restores that snapshot without resurrecting Rocket Launches. If an abort lands after only part of a restore settles, Context completes the same exact target without the stale caller signal and then replays newer explicit layer intent. Dedicated Voice Context cancellation reports a stable cancelled result plus the current Context state; generic layer visibility additionally exposes manager phase, reason, successor, and lifecycle details. Once an exact voice visibility intent commits, a newer voice turn cannot relabel it as cancelled while Context settlement completes; pre-commit aborts remain cancellable and final lifecycle mismatches remain failures. Clear Selected Layers reserves its complete captured OFF set before sequential teardown; a newer absolute request of any origin supersedes only its layer reservation and remains authoritative. A rejected layer teardown retains the truthful enabled state, rolls already-stopped siblings back to the captured pre-entry set, and aborts replay; rapid exit/re-entry serializes the full Satellite enabled-state and parameter restore before a new snapshot is taken. Contacts remains additive and restores user-enabled layers normally.

Its compact buttons use the same 176 px width as the left accordion and one consistent 50 px height, share the left stack's 52 px edge inset and measured top baseline across HUD variants, then constrain themselves against visible HUD/chrome rectangles and the remaining vertical corridor. `DISPLAY` is no longer draggable and legacy saved coordinates are ignored.
 - The right rail is labeled **DISPLAY** (formerly "MOVE") and groups, in order, HUD, DETECT, Bloom, Sharpen, 3D, Clean-UI (HUD + DETECT promoted to the top).

DISPLAY may remain open beside one contextual panel; CCTV and Context are mutually exclusive. In Tactical HUD, expanding CCTV or Context hides the other contextual launcher while DISPLAY remains independently available. The most recently opened right-rail panel owns the constrained lane even when it appears later in DOM order; passive restoration and automatic disclosure do not replace that explicit owner. Minimal and other HUD layouts retain the collapsed launchers; when their active panel exceeds the measured corridor, the rail reserves sibling heights and gaps and scrolls the active panel internally.

 - **Cockpit left-panel clearance:** the Cockpit Contact card and peripheral HUD participate in the adaptive left accordion's live obstacle measurements, including live viewport-height changes. Expanding Layers or Authoring keeps the active panel in the available upper-left corridor with internal scrolling; it does not cover the Contact card, lower Cockpit controls, or Cesium credit line. Outside Cockpit the hidden card does not alter the normal corridor.
 - **Cockpit Context scope:** the 250 km radius applies to the air/sea proximity cohorts. Installation counts come only from the currently loaded viewport and are labeled `CURRENT VIEWPORT ONLY` in the cockpit as well as the normal Context panel; neither surface presents them as a complete 250 km installation survey.
 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
-- **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls replace reliance on the `C` shortcut. RESET uses the same canonical globe route as the map and voice actions, exits Cockpit, and releases its camera ownership rather than exposing the hidden map-style top action. When the tracked commercial flight has a plausible ADSBDB route, the top of the right briefing rail shows a compact `FROM → TO` airport strip and the visor shows a centered estimated-destination chevron with its relative bearing; its destination label rounds to whole degrees in 000–359, wrapping rounded north to 000° while the chevron continues to use the relative bearing independently of label rounding; absent or implausible route data hides the strip and cue rather than guessing. The cockpit-local vision control is an interactive `PREV / CURRENT / NEXT` carousel over `NORMAL`, `CRT`, `NVG`, `FLIR`, `ANIME`, `NOIR`, and `SNOW`; its previous/next actions wrap, and activating the current value advances to the next style. Cockpit enters on the active map preset, so a Cyber FLIR map opens Cockpit on FLIR while Normal remains a distinct option instead of producing a second FLIR entry. Cockpit choices temporarily activate the existing Cesium post-process stages, while exiting Cockpit through either EXIT or RESET restores the pre-entry map style.

 - Cockpit wind-direction labels wrap after rounding to whole degrees, so a direction of 359.5° displays as `N · 0°` rather than `N · 360°`.
 - **Cockpit missing observations:** missing local weather observations remain unknown rather than being converted to zero or clear skies, in the briefing and in the cloud effects; a missing temperature drops the whole local weather record, including its wind and condition.
 - **Cockpit weather status:** the earlier multi-canvas atmospheric compositor remains fail-closed and is not attached to the live viewer. Cockpit clouds are a separate transparent WebGL pass with a capped 520×320 framebuffer, 24 ray steps, three FBM octaves, and a 12 FPS ceiling. It defaults off and starts only when local storage explicitly contains the persisted `WX ON` opt-in (`'1'`). When opted in, observations refresh after five minutes or 25 km of aircraft movement, fail transparent when unavailable or clear, and stop on exit or disable. `WX OFF` governs atmospheric rendering only: the briefing still fetches source-backed Natural Earth region, headline, and Open-Meteo local-information data, aborting and replacing any in-flight request when the selected aircraft changes. No weather effect runs in map mode and no synthetic fallback is shown.

+
+## Style
+
+- Standard German that reads naturally in Germany, Austria and Switzerland; ß where it belongs (Straße, schließen), no Swiss ss.
+- No direct address: neither «Sie» nor «du». Actions and hints use the neutral infinitive: «Erneut versuchen», «Kamera anklicken zum Aktivieren», «Zuerst eine Aufnahme wählen», «Mikrofonzugriff erlauben und erneut versuchen». "Your" becomes the article or «eigene»: «Eigener RTL-SDR-Empfänger», «Die IP-Adresse ist für diesen Sender sichtbar».
+- Nouns are capitalized, as German requires; otherwise sentence case, not Title Case: "Live Flights" → «Live-Flüge», "Provider Settings" → «Anbieter-Einstellungen». UPPERCASE English stays UPPERCASE: «LIVE-DATEN AUS», «KEINE ENTWARNUNG». In UPPERCASE, ß is written SS: «SCHLIESSEN», «STRASSENEBENE».
+- Compounds are written as one word or with a hyphen next to a name, code or English term: «Datenebene», «Wetterkacheln», «TomTom-Schlüssel», «AIS-Schiffe», «Street-View-Fallback». Do not split them with spaces.
+- Short labels, chips and HUD readouts stay short. German runs about a third longer than English, so prefer a short word or a standard abbreviation with a period over a wrapped line: REICHW., GESCHW., NIEDERSCHL., SONST., NACHR., VERST., VGL., KAL., KOMM. (a bare «KOMM» reads as the imperative)
+- The avionics codes HDG, BRG, CRS, DEST, SPD, ALT, GS, TRK, V/S, FOV and SQUAWK stay in English, as in the cockpit. Words used in a sentence are translated: heading → «Kurs», bearing → «Peilung», range → «Reichweite».
+- A dash between clauses is a spaced en dash « – »; a colon is fine where it explains: «Feed ausgefallen – neue Versuche in größeren Abständen», «SIMULIERT: Verkehrsdienst nicht erreichbar». Quotes are „…“.
+- Status and waiting messages use the neutral infinitive too: «Warten auf Aktualisierung», not «Warte auf …». Reasons inserted after a dash stay lower case: «Szene nicht gespeichert – das Projekt ist größer als 5 MiB».
+- A layer named in a sentence takes its panel name in quotes: «Die Ebene „Live-Flüge“ ist nicht aktiviert», «die Ebene „Live-Flüge“ lädt Daten für den jeweiligen Bildausschnitt».
+- Rolling time windows say their length, so they cannot read as the previous calendar period: LAST YEAR → «LETZTE 12 MONATE», LAST MONTH → «LETZTE 30 TAGE».
+- Keyboard keys are named as on German keyboards where they differ: Leertaste, Rücktaste, Umschalt; Esc, Enter, Tab and letter keys stay.
+- Decimal comma in fixed text: «M4,4», «28,2710° N». Thousands separator is a period: «1.000 km». Formatted numbers come from `Intl` and are already German.
+- Units: km, m, km/h, m/s, kn (knots, also in the cockpit), ft (feet), hPa, MW, h, min, s, T (days, in short readouts); in UPPERCASE text KM, KM/H, KN, FT, MIN, H, T («VOR {count} H»). A space between number and unit, in compact readouts too: «{value} m», «{count} min», «50 %», «{speed} KN», «{count} / 30 T». `°` sticks to the number.
+- "ago" goes before the time: «vor {count} min», «vor {value}». When a placeholder already holds a localized "ago" text (`{age}` in `STALE · cached {age}`, `{ago}`), do not add «vor» again.
+- Compass points use O for Ost: N, NNO, NO, ONO, O, OSO, SO, SSO, S, SSW, SW, WSW, W, WNW, NW, NNW; hemisphere letters N, S, O, W.
+- Routing: direction words are lowercase adverbs (links, leicht rechts, scharf links, geradeaus), so a sentence never starts with one: «Auf {road} {direction} abbiegen», «Hier {direction} abbiegen», «Weiter {direction}». «Hier», not «Dann»: the step card already says «dann {leg}» and «Nächster Schritt: …». At a fork the verb is «weiter», which also works with «geradeaus»: «An der Gabelung {direction} weiter». Roundabout exits are ordinals with a period: «die {exit} Ausfahrt» → «die 2. Ausfahrt». A lane is named by where it leads, not by its position: «Die geradeaus führende Spur benutzen», «die leicht nach links führende», «die scharf nach rechts führende» (not «halblinke» or «äußerst linke»).
+
+## Plurals
+
+A `tn()` entry needs two forms. `Intl.PluralRules('de')` picks:
+
+| Form    | Counts                      | Example   |
+| ------- | --------------------------- | --------- |
+| `one`   | 1                           | 1 Kamera  |
+| `other` | everything else: 0, 2, 1,5… | 3 Kameras |
+
+Keep the verb in agreement: «{count} Station meldet» / «{count} Stationen melden». Abbreviated units and codes do not change: «{count} NACHR.», «{count} EMPFANGEN».

+# French (`fr`)
+
+Catalog: `src/i18n/locales/fr.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+Translation source: abiyeenzo (#907); the French part of meirm's #312 was used for comparison.
+
+## Style
+
+- Standard French that reads naturally in France, Belgium, Switzerland and Canada; avoid regionalisms.
+- Address the user with "vous" imperatives: « Cliquez », « Activez », « Réessayez ». Tooltips that name an action use the infinitive: « Réduire le panneau », « Réinitialiser la caméra ». UPPERCASE HUD instructions also use the infinitive: « CLIQUER SUR UNE CAMÉRA POUR L'ACTIVER ».
+- Sentence case, not Title Case: "Live Flights" → « Vols en direct ». UPPERCASE English stays UPPERCASE, accents included: « ÉTAT », « PRÉC. ».
+- Typography: a narrow no-break space (U+202F) goes before `:` `;` `?` `!` and `%`, and inside « » quotes: `Supprimer le plan « {shot} » ?`. It keeps the sign on the same line as the word before it. Do not type a plain space there. The same narrow no-break space separates thousands in a number written into the text: « 1 000 km ». Ellipsis is `…`, not `...`. Dashes keep their spaces: « flux indisponible — réessayez ».
+- Short labels, chips and HUD readouts stay short. A standard abbreviation with a period beats a wrapped line: PRÉC., SUIV., RÉINIT., ENREG., INDISP., DIST.
+- The HUD codes HDG, BRG, CRS, FOV, DEST, SPD and ALT stay in English everywhere, as in cockpit avionics. Words are translated: RANGE → « PORTÉE », heading in a sentence → « cap », ground-track course → « route » (« ROUTE 270° »).
+- ON and OFF stay as they are on HUD toggles and chips (« CCTV ON », « PROJECTION OFF »); in a sentence use « activé » / « désactivé ».
+- Keyboard keys stay in English: Space, Esc, Enter, Tab, Shift, Backspace, H, 1–9 (« Maintenez Space pour parler », « ESC pour fermer »).
+- Units: km, m, km/h, m/s, nd (knots), ft (feet), h, min, s, with a space before the unit: « 250 km », « il y a 5 min »; in UPPERCASE text KM, KM/S, ND, FT, MIN. MW, dBZ, hPa and `°` stay. Decimal comma in fixed numbers: « 28,2710° N », « M4,4 ». Money: « 12 k$ », « 3 M$ », « 2 Md$ ».
+- "ago" goes before the time: « il y a {count} min ». When a placeholder already holds a localized "ago" text (`{age}`, `{ago}`), do not add « il y a » again.
+- Round-about exit ordinals: 1re, 2e, 3e… (« prenez la 1re sortie »).
+
+## Plurals
+
+A `tn()` entry needs three forms. `Intl.PluralRules('fr')` picks:
+
+| Form    | Counts                                 | Example              |
+| ------- | -------------------------------------- | -------------------- |
+| `one`   | 0 and 1, fractions below 2 (1,5)       | 1 caméra, 0 caméra   |
+| `many`  | 1 000 000, 2 000 000… (exact millions) | 1 000 000 de caméras |
+| `other` | everything else: 2–999 999, 2,5…       | 3 caméras            |
+
+The `many` form is the `other` text with « de » (« d' » before a vowel) after the number: « {count} de couches effacées », « {count} D'ENTRÉES INCONNUES ». When the words after the number cannot agree (an UPPERCASE readout, a list), put the number after a colon in every form: « CAPTÉS : {count} ». The same goes for a layer name whose gender and number vary: « Couche activée : {label} », not « {label} activé », or a tool name: « Outil actif : {name} », not « {name} est actif ».

+# Italian (`it`)
+
+Catalog: `src/i18n/locales/it.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+Translation source: abiyeenzo (#912).
+
+## Style
+
+- Standard Italian as in Italian software UIs. Address the user with informal "tu" imperatives: «Aggiungi», «Attiva», «Scegli», «Incolla», «Riprova». Tooltips that name an action use the same imperative: «Espandi il pannello», «Ripristina la camera».
+- Sentence case, not Title Case: "Live Flights" → «Voli live», "Space Missions" → «Missioni spaziali». UPPERCASE English stays UPPERCASE: «LIVE», «NON DISPONIBILE».
+- Quotes inside Italian text are straight double quotes: «Eliminare lo scatto "{shot}"?». Use the accented capitals (È, À) in UPPERCASE text: «VELOCITÀ», «CITTÀ».
+- Errors read as a statement, not a past participle on its own: "Search failed" → «Ricerca non riuscita»; "Could not …" → «Impossibile …». A dash that joins a cause and a hint becomes a colon: «Chiave API rifiutata: controlla AISSTREAM_API_KEY». The same goes for a label and its hint in a tooltip: «Direzione (bussola °): clic per digitare».
+- Short labels, chips and HUD readouts stay short. A standard abbreviation with a period beats a wrapped line: REGOLAZ., RILEV., INCL., ALT., VEL., STIM., PROIEZ., ESP.; PREC / SUCC for PREV / NEXT and PREVIOUS / NEXT.
+- The HUD codes HDG, BRG, CRS, FOV and DEST stay in English, as in cockpit avionics. RANGE is «PORTATA». Words used in a sentence are translated: heading → «prua» (aircraft, ships) or «direzione» (camera, buses, trams, trains), course → «rotta».
+- Keyboard keys stay in English: Space, Enter, Esc, Tab, Shift, Backspace, H, 1–9 («Tieni premuto Space per parlare», «Premi Enter per riprovare»).
+- Decimal comma in numbers written in the text, magnitudes included: «28,2710° N», «M5,2». Numbers formatted by the code follow `Intl` and need nothing.
+- Amounts: thousands, millions and billions are written out or abbreviated in Italian, not with K/M/B: «{amount} mila $», «{amount} mln $», «{amount} mld $».
+- Units: km, m, km/h, m/s, kn (knots), ft (feet), h, min, s; in UPPERCASE text KM, KM/S, KT, FT, MIN, H. "m" is always metres, so minutes are «min» («5 min fa»). MW stays MW. `°` and `%` stay.
+- "ago" goes after the time: «{count} min fa». When a placeholder already holds a localized "ago" text (`{age}`, `{ago}`), do not add «fa» again.
+- A feature name used as a sentence subject gets a head noun so the verb agrees: «La modalità Missioni spaziali isola…», «Il pannello Impostazioni provider è disattivato…», «Il livello {layer} è attivo…», «Lo strumento {name} è attivo…». A short card title with a placeholder name puts the state after a colon: «{label}: attivato». The same goes for a placeholder list of names: «Attivazione recente: {layers}». A count in a plain `t()` entry (no plural forms) that can be 1 goes after a label, so nothing has to agree with it: «Record accettati: {accepted} su {raw}».
+- English loanwords that Italian UIs use as they are stay in English: feed, live, cockpit, briefing, preset, overlay, layout, snapshot, tile, provider, timeout, payload, bloom, scope.
+
+## Plurals
+
+A `tn()` entry needs three forms. `Intl.PluralRules('it')` picks:
+
+| Form    | Counts                                 | Example                 |
+| ------- | -------------------------------------- | ----------------------- |
+| `one`   | 1                                      | 1 telecamera            |
+| `many`  | 1 000 000, 2 000 000… (exact millions) | 1 000 000 di telecamere |
+| `other` | everything else: 0, 2–999 999, 1,5…    | 3 telecamere            |
+
+The `many` form is the `other` text with «di» after the number when a noun follows: «{count} di telecamere caricate», «{count} DI CHIAVI IN ATTESA». When no noun follows the number («{count} vicine», «{count} RICEVUTI»), `many` repeats `other`. Nouns that do not change in the plural keep one form for all three (`{count} file`, `{count} data center`), with «di» in `many`.

+# Japanese (`ja`)
+
+Catalog: `src/i18n/locales/ja.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+Translation source: abiyeenzo (#913).
+
+## Style
+
+- Sentences use です／ます: 「キーを保存しました」, 「もう一度お試しください」. Labels, buttons and HUD chips are short nouns or verb stems without a final 。: 「再試行」, 「保存」, 「ライブ」, 「オフ」.
+- Japanese has no case: an UPPERCASE English label becomes the same short Japanese label. Codes, units and names stay in their own case (HDG, ADS-B, km).
+- Full-width punctuation in Japanese text: 、。：？！（）「」. Quote names and titles with 「」: 「{shot}」を削除しますか？ Keep `·` as the HUD separator, `…` for an ellipsis and `—`, `→`, `↗` as in English. A dash inside a sentence becomes 。 or ：.
+- Button names cited in running text go in ［］: ［次へ］を使ってください.
+- No space between Japanese and Latin letters, digits or a `{placeholder}`: 「AIS船舶」, 「Spaceを長押しで話す」, 「{count}件」, 「{name}を表示」.
+- Two exceptions keep the space: a Japanese label before its value in a readout (「雲量 {pct}%」, 「ステーション {id}」, 「高度 {altitude}」), and the state words in toggles (「CCTV オン」, 「ラジオ オフ」).
+- Waiting states are 「X待ち」, not 「Xを待機中」: 「観測データ待ち」, 「進路/予報円は第{number}報待ち」, 「RTL-SDRデバイスの接続待ち…」. 待機中 is for something on standby with no object: 「フィード待機中」, 「音声待機中」.
+- Key names keep their own case in running text and hints: Tab, Enter, Space, Esc (「Tabでプレビュー · Enter / Spaceで選択」). Text that CSS upper-cases shows them in capitals, as in English.
+- Loanwords are katakana with the long-vowel mark, as in Microsoft and Apple style: ユーザー, ブラウザー, ビューアー, プロバイダー, レイヤー, フィルター, モニター, パラメーター. Pick one katakana form per term and keep it (see the glossary).
+- Product, provider and dataset names stay in Latin script: Google Maps, Cesium ion, OpenSky, CelesTrak, NASA FIRMS, Sentinel-2, KartaView. Google's own product names use Google's Japanese, joined like any Latin word: Googleストリートビュー. Nepal place names in the Bhote Koshi scenes stay in Latin script, as in zh-CN; country and well-known city names are translated (ネパール, 東京, オースティン).
+
+## Numbers, units and dates
+
+- Units: km, m, km/h, m/s, kt, ft, mph, hPa, MW, dB, °, % stay as written, with the English spacing (「250 km」, 「{frp} MW」, 「95 kt」). Code-built cockpit distances follow this too (`cockpitUnitCase` skips the HUD upper-casing for ja, as for zh). The cockpit's own speed caption is the HUD code KT, in 対地速度 · KT and under the readout.
+- Number ranges keep the English en dash, not ～: 「2–6日ごと」, 「50–99%」, 「南緯25°–北緯80°」.
+- Time units are words written straight after the number: 秒, 分, 時間, 日 (「5分前」, 「{count}時間」, 「1時間5分」). `formatQuantity` and `formatRelativeTime` drop the space for Japanese unit words, so code-built values match the catalog.
+- Counters follow the thing counted: 機 (aircraft), 隻 (ships), 基 (satellites), 台 (cameras, vehicles), 局 (stations), 件 (records, results, events), か所 (sites), 個 (generic). Prefer a counter to a bare number.
+- Dates come from `Intl` and read year first: 2026年8月26日. Coordinates in prose are 北緯 / 東経; HUD hemisphere letters stay N, S, E, W.
+
+## Plurals
+
+`Intl.PluralRules('ja')` has one category, `other`: a `tn()` entry has only that form. Put the counter next to the number: 「航空機{n}機」, 「船舶{n}隻」, 「メッセージ {count}件」.

+# 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).

+# Ukrainian (`uk`)
+
+Catalog: `src/i18n/locales/uk.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+Translation source: meirm (#312).
+
+## Style
+
+- Address the user with polite imperatives: «Натисніть», «Увімкніть», «Спробуйте ще раз».
+- Sentence case, not Title Case: "Live Flights" → «Рейси онлайн».
+- Ukrainian norms, not Russian calques: «у радіусі», «за посиланням», «надто довгий», «потім», «вигляд» (a camera view: «вигляд згори»), «стеження» (tracking); prepositions alternate у/в and і/й by euphony.
+- The apostrophe is always ʼ (U+02BC): обʼєкт, звʼязок, памʼять. Not ' or ’.
+- Quotes inside Ukrainian text are «ялинки»; a button or layer name inside a sentence goes in them: Увімкніть «Вуличні знімки».
+- In short labels, a standard abbreviation with a period beats a wrapped line: ПОПЕР., ДАЛЬН., КАЛІБР.
+- Units: км, м, км/год, м/с, вуз (knots), фт (feet), год, хв, с, МГц, дБ, гПа; in UPPERCASE text КМ, М, КМ/С, ВУЗ, ФТ. MW is МВт in any case. `°` and `%` stay. Decimal comma in coordinates written as text: 28,2710° пн. ш.
+- Coordinates: пн. ш. / пд. ш. / сх. д. / зх. д.; the HUD hemisphere letters are Пн, Пд, Сх, Зх.
+
+## Plurals
+
+A `tn()` entry needs four forms. `Intl.PluralRules('uk')` picks:
+
+| Form    | Counts                   | Example    |
+| ------- | ------------------------ | ---------- |
+| `one`   | 1, 21, 31, 101…          | 1 камера   |
+| `few`   | 2–4, 22–24, 32–34…       | 3 камери   |
+| `many`  | 0, 5–20, 25–30, 111–114… | 5 камер    |
+| `other` | fractions: 1.5, 2.25…    | 1,5 камери |
+
+`other` takes the genitive singular: 1,5 кадру, 1,5 літака, 1,5 ключа. When a word next to a number cannot agree in every form, move the number after a colon instead: «поруч: {count}», «відповідей: {responses}». The same trick keeps place names and tool names out of a preposition's case: «звідки: {origin}», «Активно: {name}».
