### Rules
- Always include x-default pointing to the primary language
- Every page must reference all other language versions
- URLs in hreflang must be crawlable

## 4. Open Graph and Twitter Card
- og:title, og:description, og:image (1200x630px), og:url, og:site_name, og:locale
- og:locale:alternate for each additional language
- twitter:card = summary_large_image

## 5. Semantic HTML
- header for navigation
- main for primary content
- section with aria-label for each content block
- footer for footer
- h1 only once per page (site name in hero)
- h2 for section titles
- img with meaningful alt text in every language
- loading=lazy for below-fold images

## 6. URL Path Multi-language Strategy
- www.example.com/en for English
- www.example.com/kr for Korean
- www.example.com/jp for Japanese
- Each language path serves complete HTML with its own TDK
- hreflang tags connect all versions
- Internal links use language-prefixed paths
