Browser cache and storage

What happenedNewest first

Two habits worth keeping

While you build: hard refresh with Ctrl+Shift+R, or Cmd+Shift+R on a Mac, so you see the file you actually saved.
When you ship: treat everything above as a convenience. Storage belongs to this browser on this machine, it does not travel with the file, and a private window or a cleared history wipes it. Anything the user cannot afford to lose needs an export to a file.
