- Custom JSON-LD schema builder: per-article textarea for arbitrary structured data with JSON validation. Closes #70 - AI-powered meta generation: Generate with AI buttons for OG title and description, supports Claude and OpenAI APIs. Closes #71 - XML sitemap: auto-generates sitemap.xml on article save, respects noindex directives. Closes #72 - Per-platform image resizing: Twitter 1200x600, Pinterest 1000x1500, WhatsApp 400x400 alongside default Facebook 1200x630. Closes #74 - DB migration 01.05.00: adds custom_schema column
