Interface localization

Repovio ships its web interface in English (en), German (de), Spanish (es), French (fr), Italian (it), Dutch (nl), Polish (pl), and Portuguese (pt). The language menu in the application header is available to every signed-in user. Choosing a language saves the preference in the repovio-locale browser cookie and applies it on future visits.

English is the deterministic default and fallback. When a browser preference or saved cookie does not identify a supported locale, Repovio renders English. Date, time, and number formatting use the selected locale.

Sign-in controls and language flags

The sign-in and first-administrator setup pages offer a language selector below the form with the active language and its flag. The selector stays busy while a language loads. A separate theme button cycles through System, Light, and Dark and persists the preference. Its icon shows the current preference; its tooltip and accessible name describe the current preference and the next action.

The language menu displays decorative local SVG flags alongside native language names. Names remain the accessible labels; flags do not replace them. The locale-to-country mapping is: en → GB, de → DE, es → ES, fr → FR, it → IT, nl → NL, pl → PL, pt → PT.

Assets in apps/web/public/flags come from flag-icons v7.5.0, under the included MIT license. They require no external image requests. When adding a locale, add its flag asset and mapping in useLocales too.

Adding or updating a locale

1. Add or update apps/web/i18n/locales/<locale>.json using en.json as the complete key reference.
2. Register its locale code, file name, and native display name in apps/web/nuxt.config.ts.
3. Keep all message keys present in en.json; the web test suite checks this parity for every shipped locale.
4. Add English and German messages for every new user-visible interface string, then add the corresponding translation to every shipped locale.
5. Run pnpm --filter @repovio/web test, pnpm --filter @repovio/web typecheck, and the affected Playwright test.

Provider names, repository names, workflow names, and other provider-supplied data remain unchanged because they are not Repovio interface copy.
