I know this is marginal, but it bothers me
The Guix manual is not readable on mobile phones. It seems to me that the viewport declaration is missing
The effect is that on a mobile phone you have to pinch and zoom and scroll all over in order to read.
That is, it's substantially impossible to casually consult the manual on a mobile phone.
Because I don't know the first thing about Texinfo, I don't know if this can be accomodated by the Guix project (maybe the build phase could feed Texinfo a revised html template) or of this requires the whole Texinfo project to be patched.
