Legend

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

I wonder if we should show the Start with free regardless of if they choose a paid domain or not? BigSky is a paid feature so we give them the same free escape hatch even if the selected a free domain.

Currently if i select a free domain, I don't get the escape hatch

That makes sense! I'll investigate how to do that.

We'll still have one more variation. Context: p1738269257951999/1738217832.782999-slack-C085HCWCEDN

This PR doesn't include any feature flag or experiment assignment checks, so I was able to rebase onto trunk
