This webpage is devoted to an artwork inspired by the Babylonian creation myth: The Enûma Eliš. Essentially it's a gallery that uses some Elm code to display and describe aspects of each of the panels on seven separate clay tablets that make up the piece.
Feel free to continue blocking external scripts. I don't track or use anything not from this domain. My CSP is pretty damn tight:
default-src 'none'; img-src 'self'; script-src 'self'; style-src 'self'; font-src 'self'; frame-ancestors 'none'; form-action 'self'; base-uri 'self'; manifest-src 'self'
which you can verify at Mozilla Observatory. Note that I take security as seriously as you, achieving an A+ with a score of 120/100. Feel free to look over the code listed above if you're skeptical, and please file an issue if you notice anything untoward.
If these details haven't convinced you to enable local script sources, then I bid you farewell, and safe travels. Remain vigilant!
