It solves the dead-link-preview problem where recipe URLs pasted into Discord or Slack show a generic wiki logo and the URL bar, which kills click-through. The signal is share analytics: links with rich previews get measurably more clicks on Discord than plain links, and the recipe URL is already the most-shared asset in the server's community. Caching by recipe-id for 7 days is the right balance — recipes change rarely, but you do not want to serve a stale preview for a renamed item. ## Implementation tips 1. Generate OG images server-side: 1200x630 PNG with item icons + recipe name. Use satori or @vercel/og. 2. Cache the PNG by recipe-id — recipes don't change often, cache for 7 days. 3. Add proper og:image, og:title, og:description meta tags on the detail route.
