Question 1

What is mui.com's Open Graph type?

Accepted Answer

mui.com declares `og:type` as `website`. This tells Slack how to categorize the content when generating a preview.

Does mui.com declare image dimensions?

mui.com sets `og:image` but does not include `og:image:width` and `og:image:height`. Explicit dimensions let platforms render the preview faster without downloading the image first.
