Open Graph image size

Use 1200×630 pixels (≈1.91:1). Smaller images get upscaled poorly; much larger files waste bandwidth without improving the crop.

Platform notes

• Facebook / LinkedIn — 1200×630 is the documented sweet spot
• X / Twitter — use summary_large_image with the same canvas
• Slack / iMessage — follow OG tags; 1200×630 remains safe
