I’m Andy - @evilpiper is my test account 
So if you go to my profile twitter.com/evilpiper you’ll see the tweet right under my pinned tweet with photo at the top. It looks like this:

Click the View Summary link and the card shows beneath the tweet.
Similarly, if you go to the @evilpiper profile in one of our Twitter mobile clients, and tap on the tweet, you will see the card underneath the text.
In addition to post code here, you need to surround it with code tags, otherwise it will not show up. I’ve modified your two posts to include the tags so your meta tags from the html show up.
