HangerThem
64ae30b545
- Add sitemap.ts and robots.ts - pageMetadata() helper: consistent title, canonical URL, Open Graph, Twitter card and feed alternate on every page - Generated OG images: a site card, and per post either the cover image or a branded title card (pre-rendered at build) - BlogPosting JSON-LD on post pages - Fail fast with a clear error when SITE_URL is missing Content loading: - Validate post frontmatter at build time and normalize dates to ISO (fixes invalid <time datetime> values) - Add draft: true support (drafts only render in development) - Cache markdown rendering so metadata and page share one render - Replace the three copy-pasted about/projects/setup pages with a shared MarkdownPage component
