HARDCODED STRINGS DETECTED
src/components/Header.tsx:14 → "Welcome back, "
src/pages/checkout.tsx:87 → "Free shipping on orders over $50"
src/utils/date.ts:23 → new Date().toLocaleDateString() ← no locale
PLURAL ISSUES
pt-BR → cart.items_count: missing 'other' form
es → notification.unread: uses 'plural' (nonstandard), should be 'other'
ORPHANED KEYS (in pt-BR but not in en — likely stale)
auth.login_with_facebook ← Facebook login removed 3 months ago
checkout.cod_payment ← COD feature removed
