This PR is:

• Adding a new domain
• Updating existing domain size
• Changing domain name
• Removing existing domain from list
• Website code changes (512kb.club site)
• Other not listed

• I used the uncompressed size of the site
• I have included a link to the Cloudflare report
• This site is not an ultra minimal site:
  already not, see music page -- actively working on the other pages
• The following information is filled identical to the data file

I confirm that I have read the FAQ section, particularly the two red items around minimal pages and inappropriate content and I attest that this site is neither of these things.

• Check to confirm
