 ## Localization
 
 - NEVER hardcode user-visible English strings in production code. ALWAYS use an i18n key for visible copy, placeholders, accessible labels, tooltips, menus, dialogs, toasts, empty states, and displayed errors.
+- Feature work adds English source strings only. Leave non-English keys absent so the runtime English fallback applies; translations land separately after language review.
+- Render count-sensitive copy only through `language.plural(baseKey, count, params)`. Never select or pass `.zero`, `.one`, `.two`, `.few`, `.many`, or `.other` variants to `language.t(...)`.
 - 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.

 ## Localization
 
 - NEVER hardcode user-visible English strings in production code. ALWAYS use an i18n key for visible copy, placeholders, accessible labels, tooltips, menus, dialogs, empty states, and displayed errors.
+- Feature work adds English source strings only. Leave non-English keys absent so the runtime English fallback applies; translations land separately after language review.
+- Render count-sensitive copy through `i18n.plural(baseKey, count, params)`. Never select or pass `.zero`, `.one`, `.two`, `.few`, `.many`, or `.other` variants to `i18n.t(...)`; `pluralForm(...)` is reserved for components that animate individual grammatical forms.
 - 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.
 - 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`.

 ## Localization
 
 - NEVER hardcode user-visible English strings in production code. ALWAYS use an i18n key for component defaults, visible copy, placeholders, accessible labels, tooltips, dialogs, toasts, empty states, and displayed errors.
+- Feature work adds English source strings only. Leave non-English keys absent so the runtime English fallback applies; translations land separately after language review.
+- Render count-sensitive copy through `plural(baseKey, count, params)`. Never select or pass `.zero`, `.one`, `.two`, `.few`, `.many`, or `.other` variants to `t(...)`; `pluralForm(...)` is reserved for components that animate individual grammatical forms.
 - 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.
 - 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`.
