I'm in a situation where I legally have to add a copyright notice to the top of my files and while I know how I can comment inside either template, script or style, I couldn't find documentation regarding how to do it outside these.
Based on the structure of the file, I assume the standard HTML comment (<!-- Hi there! -->) should work, and it both: a.) seems to work and b.) my syntax highlighter accepts it.
However, I'd like to be sure about it and understand how and why it works this way, I was surprised it is seemingly not covered in the Vue docs.
.vuefiles as HTML, so you should use HTML comments outside the standard SFC blocks.
