Every locale formatter takes the language as an argument. Under the React
Compiler a formatter that read the i18n singleton was memoized on its other
arguments, so a card kept "2 hr 4 min" after a switch to Hungarian; plexLang()
had the same flaw and left Plex queries in the old language. Components now
take the language from useTranslation, and the signature makes forgetting it
a type error.
- ratings, file sizes, stream stats: the language's decimal mark ("8,3")
- view and subscriber counts compact in the language ("1,2 E")
- seconds as the language's unit ("6 mp") in the sliders and the stats
- a person's birth and death dates as dates, not ISO strings
- A-Z lists by the shown name in the language's alphabet (compareText),
the tag catalog re-sorted by its translated names
- lint local/locale-format (was date-format) also refuses Intl.NumberFormat
outside lib/format.ts, localeCompare, and a component reading the language
off the i18n singleton

// The up-next end-card's core behaviour (E6 S4): the countdown that auto-advances at ~10s (the whole
|
|
// point — it REPLACED the old instant jump, so a regression that fires early or never is exactly the
|
|
// bug to guard), the "Play now"/Cancel controls, and the episode heading's null season/episode
|
|
// fallback. i18n is key-passthrough; `../lib/api` is mocked so no network runs; the countdown uses
|
|
// performance.now, which vitest's fake timers advance alongside setInterval.
