21MCap.com: Bitcoin supply cap countdown and other bitcoin sats

I started off building a simple one page, no code BTC site as an experiment in using carrd.co, but then I found myself down a rabbit hole and "no code" became "low code" with the introduction of real time bitcoin data from blockchain.info and calculations built in JS. The code is novice, but it gets the job done - furthermore it helped me realize how flexible carrd is which has led me to using it on a more robust project I’m tinkering on. This was my first time using carrd.co and I fell in love. Thank you @ajlkn Let me know what you think! Future improvements - I relied on a static block time, I should rework this to use an average block time over the most recent 12 months. Also let me know if there are other Bitcoin data points you think I should add.
