Add Localization

Quick Steps

1. Create locale JSON from English

cp src/locales/en.json src/locales/{code}.json

Use the ISO 639-1 language code (e.g., es, fr, de, ja, pt, zh).

2. Translate all string values

Edit the new JSON file. Only translate values, never keys.

✅ Correct:

"wizard.step1.tagline": "Genera un documento personalizado..."

❌ Wrong — don't change keys:

"wizard.step1.tagline_es": "Genera un documento personalizado..."

3. Preserve {{ variable }} placeholders

Keep placeholders like {{ appName }}, {{ platformDesc }}, {{ deviceType }} unchanged in the translated text.

4. Build

make build

The Go build tool detects every JSON file in src/locales/ and generates the HTML and JavaScript for each locale.

Open public/index.html — the language switcher dropdown now includes the new language.

Validation Checklist

• JSON file is valid (no trailing commas, no duplicate keys)
• All {{ variable }} placeholders preserved
• UI labels, placeholders, help text translated
• Legal templates translated (requires native-speaking legal review)
• FAQ and disclaimer content translated
• Platform vocabulary translated (device types, OS, browser strings)
• Language appears in the dropdown
• make build succeeds
• make check passes (Go vet, build, golden, and Playwright checks)

Important Notes

• Legal text needs professional review: Have a native-speaking lawyer review legal template translations.
• Don't translate third-party service names in thirdpartyservices.yml — only the name field in the locale JSON if you add locale-specific names.
• Meta tags (meta.* keys) are updated dynamically via JS after page load.
