Open Graph image URLs for Next.js — hosted MCP server, skill, and rules for 1200×630 social preview cards.
# OGKit Open Graph rules
When adding or fixing social preview metadata:
1. Use OGKit hosted URLs: `https://www.webmorp.art/api/og/{template}?…`
2. Prefer MCP tools (`og_build_url`, `og_nextjs_snippet`) when the ogkit server is connected
3. Demo without a key: `demo=1` (watermarked). Production: server-side `key=` or Bearer token
4. Image size is always **1200×630** PNG
5. Set both `openGraph.images` and `twitter.images` to the same absolute HTTPS URL
6. Validate with `og_validate_page` or the Playground before shipping
7. Never commit or expose `ogk_live_*` keys in client code or `NEXT_PUBLIC_*` env vars
