 - Modern Standard Arabic, neutral across regions. Address the user with plain imperatives: «انقر»، «فعّل»، «أعد المحاولة».
 - Arabic has no letter case: an UPPERCASE English HUD label becomes the same short Arabic label. Keep labels as short as the English: «مباشر»، «متقادم»، «متوقف».
-- Status words in progress use «جارٍ …» («جارٍ التحميل»، «… جارٍ تشغيل اللقطة»); finished actions use the passive («تم الحفظ»، «أُلغي التحميل»). Data that refreshes itself «يُحدَّث» (يتحدّث means "speaks"). A sentence about a `{placeholder}` whose gender and number vary stays impersonal: «{layers}: تم التفعيل للتو».
-- A label followed by its value takes a colon, so it does not read as a sentence: «الصوت: نشط»، «السياق: {value}».
+- Status words in progress use «جارٍ …» («جارٍ التحميل»، «جارٍ الضبط»، «… جارٍ تشغيل اللقطة»), so a status chip never reads as the command next to it («ضبط» is the TUNE button); finished actions use the passive («تم الحفظ»، «أُلغي التحميل»). Data that refreshes itself «يُحدَّث» (يتحدّث means "speaks"). A sentence about a `{placeholder}` whose gender and number vary stays impersonal: «{layers}: تم التفعيل للتو».
+- A label followed by its value takes a colon, so it does not read as a sentence: «الصوت: نشط»، «السياق: {value}»، «الاحتواء: {percent}%». A named mode or control quoted in a sentence takes «»: «يظهر في وضع «كثيف» فقط».
 - Arabic punctuation in Arabic text: ، ؛ ؟ and «» for quotes. Keep `·` as the HUD separator, `—` with spaces, and `…`.
 - Arrows that show a sequence point the way Arabic reads: «الإشارات ← الأخبار ← المحلي», «{origin} ← {destination}».
 - Product names, provider names and codes stay in Latin letters: Google, Cesium ion, CelesTrak, NOAA, FIRMS, AIS, ADS-B, GNSS, CCTV, HUD, CRT, NVG, FLIR, WHOT/BHOT, Ironbow, Street View, Mapillary. Aviation and camera abbreviations stay Latin too: HDG, FOV, BRG, CRS, GS, TRK, V/S, SQUAWK. Local place names from the Bhote Koshi scene (Rasuwagadhi, Bidur, Timure…) stay Latin; well-known cities and countries are written in Arabic (أوستن، طوكيو، نيبال).

 - Latin runs inside Arabic sentences (product names, codes, `{placeholders}` filled with English data) are isolated by the bidi algorithm; write them as plain text, without manual direction marks.
 - Position counters: a translated counter says «من» («القناة {index} من {total}», «الإطار {index} من {total}»); a spaced slash between two isolated numbers swaps them in right-to-left text. Counters the code builds from bare numbers (`01 / 25`, `1 / 3`) are shown left to right by `rtl.css`.
 - Code stays left to right: the JSON fields of the scene editor are LTR in every language.
-- Comparison signs `<` and `>` are mirrored glyphs in right-to-left text («< 2%» shows as «> 2%»). Write them as words: «أقل من 2%»، «أكثر من 10%»، «أقل من ساعة». A legend's open upper bound («300+», «-40») is isolated by `formatScaleLabel()`, so its sign stays where it is written.
