src/i18n/resources.ts

// Translation resources for downstream library consumers.
//
// This module is intentionally separate from `src/i18n/index.ts` so that the
// 1 MB `translation.json` does not enter the app's eager dev/prod graph. The
// app initialises i18next with `i18next-http-backend`, which fetches
// `/locales/<lng>/openhands.json` at runtime; it never needs the embedded
// resources object.
//
// Library consumers (`@openhands/agent-canvas/i18n`) can still import
// `translationResources` from `src/i18n/index.ts`, which re-exports from here.
// The re-export is `export … from`, which rollup is able to drop when the
// app build does not reference `translationResources`.
