Angular's LocalizationService reads `Country = baseHref[1..3]` and
`Language = baseHref[4..6]` — both halves are the same 2-letter
language code (`/ru-ru/`, `/en-en/`, `/zh-zh/`, …), confirmed by
the spec fixtures using `/en-en/onlineboard/...`. The previous
shipping codes mixed in IETF region codes (`en-us`, `ja-jp`, `ko-kr`,
`zh-cn`) which do not match the customer's URL surface.
Renamed:
en-us → en-en
ja-jp → ja-ja
ko-kr → ko-ko
zh-cn → zh-zh
The `LANGUAGE_TO_LOCALE_CODE` table now mirrors Angular exactly.
Resolver/hreflang tests + layout 404 message updated.
- URL surface now matches Angular: `/ru-ru/`, `/en-us/`, `/zh-cn/`, …
(BCP-47). Bare short codes still work — the [lang]/layout auto-
promotes them with a replace navigation. Internally everything that
needs the short language (i18n file lookup, API path segment,
Accept-Language header, dictionary `title[lang]` key, Intl
formatters) reads it through the new `useLocale()` hook, which
returns both `locale` (BCP-47) and `language` (short).
- ApiClient.locale is now mutable and is updated from the [lang]
layout whenever the URL locale changes — was hard-coded to "ru" in
the root layout before, so backend responses for /en/... still came
back in Russian. Cities / airports / flight statuses now arrive in
the active language.
- All 21 empty EN translation keys filled in (AIRPLANE.*, BOARD.
PREVIOUS-FLIGHT, SCHEDULE.FILE-NAME, SEO.SCHEDULE.*, SEO.FLIGHTS-
MAP.*, SHARED.FLIGHT-TRANSFER-PLURAL-*, SHARED.WEEK_FORMAT-WRONG)
so /en-us renders without falling back to raw keys.
- Added BOARD.LOAD-FAILED-TITLE / -MESSAGE keys (RU + EN) and removed
the three hardcoded Russian error strings from the search-page
error card.
- FlightStatus now reads `FLIGHT-STATUSES.{Status}` from i18n instead
of hardcoding the Russian labels.
- FlightCard's OperatorLogo now picks the en/ru carrier-logo variant
from `useLocale().language` instead of always passing "ru" — the
Aeroflot/Rossiya logos display in the active language where
variants exist.
- registerPrimeLocales(): all 9 supported languages get a PrimeReact
`addLocale` entry at module load (RU + EN hand-curated, others built
from Intl). Calendar/AutoComplete widgets switch with the URL.
- ErrorBoundary catches outside the i18n provider, so it now ships
its own minimal localised string table keyed off the URL locale —
no more "Something went wrong" leaking on the Russian site.
- Hreflang URLs now emit BCP-47 (`/en-us/...`) while `hreflang="en"`
stays the short Google-friendly form.
- Datetime helpers accept either short or BCP-47 locale (`isRussianLocale`)
so callers can pass through whatever the route hands them.
