i18n

Core rules

• English (en) is the source catalog. Do not alter keys; only update translations.
• Preserve placeholders and ICU syntax exactly (e.g., {name}, {count, plural, one {...} other {...}}).
• Keep technical terms in English when appropriate (API, TypeScript, React).

Translation updates

• Update src/lib/i18n/locales/{locale}/messages.json only; do not edit compiled outputs by hand.
• Use ./scripts/put-transtation.js to safely update a specific entry without loading the full file into context.

Verification

• Run pnpm lingui:extract when new messages are added.
• Run pnpm lingui:compile to regenerate compiled catalogs.
• Run scripts/lingui-check.sh to verify no missing translations.
• Run scripts/i18n-check-key-equals-translation.sh to ensure key != translation in all locales.
