feat(07-02): enrich blog article page with full SEO meta + Article/Breadcrumb JSON-LD
- D-15: useSeoMeta extended with ogImage (absolute via resolveOgImage),
ogUrl (canonical), ogLocale + ogLocaleAlternate (emitted only when bilingual
pair exists), twitterCard + twitterImage, article:published_time,
article:modified_time (fallback to date when updated absent — D-13),
articleAuthor
- SEO-11/SEO-15: useSchemaOrg([defineArticle, defineBreadcrumb])
— Article author/publisher reference global Person via @id=#killian
(from app/utils/seo-person.ts KILLIAN_PERSON_ID), image mirrors ogImage,
mainEntityOfPage = canonical; BreadcrumbList emits Accueil → Blog → title
- Pitfall 7: altExists query via queryCollection('blog_en'|'blog_fr') with
literal collection names (Vite extractor constraint)
- inLanguageTag computed cast to satisfy overly narrow defineArticle typings
without changing runtime emission
- Validated SSR: curl /fr/blog/test-kotlin-syntax returns og:image absolute,
article:published_time, Article JSON-LD (author @id=#killian), BreadcrumbList 3 items
