Better embed/unfurl previews

[tigt]

[6:30 PM] mpeg: It seems like notion wikis are not showing the correct info for https://markojs.com/ since the page lacks open graph tags it seems to default to grabbing that google home text because it has a class that contains "description", the image is also not the logo because some OG previews don't support svg as the image, so it seems like it's finding the first png in the page and showing that instead

[6:31 PM] mpeg: hmm discord not showing the preview at all, I guess also because of the lack of OG tags?
