Moved my first site onto my own domain

The spelling site started as one file on Netlify. Today it moved:

• GitHub now holds the code and remembers every version.
• Vercel publishes it automatically whenever I commit a change.
• Namecheap points sutton.pfinn.org at Vercel with a CNAME record.

I split the word list into its own file, words.js, so weekly updates can’t break the games. It now keeps every week, and Sutton can practice any mix of them.

Things that tripped me up: I looked at the wrong site when checking my first change, and the domain showed “Invalid Configuration” until I actually added the DNS record. File names matter too. index(5).html is not index.html.
