This is an experiment in self-contained HTML files, inspired by TiddlyWiki.
The idea is to have a to-do list stored entirely in an HTML file.
Open selfie.html in your web browser, at a URL like file:///d/code/selfie/selfie.html.
Add or delete notes. Then, via your browser, overwrite selfie.html with itself. Reload the page, and your changes will remain.
