The bitsugar landing page, served at https://bitsugar.io.
It is one hand-written index.html with its styles inline, plus logo.png.
GitHub Pages serves the root of main at the domain in CNAME. There is no
build step, test suite or formatter.
Edit index.html and open it in a browser to check it. A merge to main
publishes the site, with no build, preview or required review in between, so
look at the page before you merge, not after.
