LEARNING OBJECTIVES ⌵
- Understand why static, generic Open Graph images yield low social CTR compared to customized dynamic preview cards.
- Implement automated Edge/Serverless OG image generators using
@vercel/og, Satori, or HTML Canvas. - Dynamically render article titles, authors, read times, and branding into a $1200 \times 630\text{px}$ image.
- Cache generated PNG/WebP social cards at the CDN edge.
