- i18next + react-i18next + expo-localization: device-locale detection,
an MMKV-persisted DE/EN/Automatisch override (mirrors web's cookie-only
locale, no backend field needed), and a language switcher on the Pets
tab next to the theme toggle
- every screen and shared component converted from hardcoded German
strings to translation keys; de.json/en.json kept in exact key-parity
(218 keys each, verified programmatically)
- backend: src/trpc/init.ts now accepts an x-locale header as a fallback
locale source (cookie still wins, web unaffected) since mobile has no
cookie jar to set NEXT_LOCALE in; mobile's tRPC client sends the
current language on every request
- fixes a latent bug: species/breed pickers were hardcoded to locale
"de" while every other pet query resolved names via ctx.locale's
default (English, since mobile never sent a locale cookie) — both now
use the same current-language value
- expo-localization is a new native module (config plugin) and needs a
native rebuild to actually link; deviceLocale() falls back to English
instead of crashing when it isn't linked yet, so the app stays usable
before that rebuild happens
Needs a NAS deploy (src/trpc/init.ts is shared backend code) before the
x-locale fallback and the species/breed locale fix take effect for mobile.
