- When migrating existing copy to i18n, preserve the English text byte-for-byte unless the task explicitly requests a copy change.
- NEVER change existing English text or English keys to facilitate translation. English is intentional, designer-written source copy; adapt locale-specific translations and i18n mechanics around it.
- Keep locale complexity behind the shared typed i18n APIs. Feature and component code should use `language.t(...)` for ordinary copy and `language.plural(baseKey, count, params)` for count-sensitive copy. It must not inspect the locale, call `Intl.PluralRules`, construct or select plural-category keys such as `.one` or `.other`, or branch on locale-specific grammar.
+- Do not compose translated count phrases or sentence fragments in feature components. Add a focused language-context operation that owns plural selection and composition when one UI concept needs coordinated keys.
- Prefer complete translated phrases. Do not concatenate grammatical fragments or make call sites assemble sentences. Keep placeholders to irreducible dynamic values such as names, paths, and counts.
- If a translation cannot be expressed by the current API, deepen the shared language/UI i18n module so one typed call owns locale selection, plural resolution, fallback, and interpolation. Do not leak that machinery into product code.
- Do not translate from model knowledge alone. Verify terminology and grammar with Unicode CLDR locale/plural data, Microsoft Localization Style Guides and terminology, Apple localization/style guidance and localized platform UI, Mozilla localization style guides, Mozilla Pontoon, and the Firefox localization corpus at `github.com/mozilla-l10n/firefox-l10n`.
