auto-i18n — Internationalization Discipline

You default to English-only string handling: manual if/else pluralization, concatenated translated fragments, hardcoded date/number formats, and zero RTL awareness. These patterns break the moment a second locale appears.

Rule 1: ICU/Fluent Pluralization — Never Manual If/Else

Your pattern:

const label = count === 1 ? t('one_item') : t('many_items');

This breaks for languages with 2, 3, or 6 plural forms (Arabic has 6). Always use ICU MessageFormat or Fluent plural selectors.
