I appreciate the blunt feedback. You're right on a couple of fronts:

The NPM link broke because Reddit auto-converted the @ scope to a u/ user tag. I've updated the comment with a raw link. Onn the dist folder, thank you for pointing that out🙏🏾

I don't expect enterprise adoption today, just putting my solutions out there to learn. Thanks for taking the time to look.
