Phase 3 (Implement). Load when adding user-facing text to ensure localization-readiness from the start.

Modern API (String Catalogs)

String(localized:)

// Basic localized string
let greeting = String(localized: "welcome_message")

// With default value and comment for translators
let greeting = String(localized: "welcome_message",
                      defaultValue: "Welcome back!",
                      comment: "Greeting shown on home screen after login")
