Case-sensitive meta tag property value

I noticed some pages had an uppercase meta property value such as `<meta property="Description"`. It might have to be lowercase (`description`) if it's case-sensitive. Vercel is also reporting the description is missing:

<img width="998" height="360" alt="description missing in OG report" src="https://github.com/user-attachments/assets/a0ce2950-a379-451f-bab7-33e62e92fcfa" />
