When you write nonsense as font name without setting a upright font nothing will show up in your document because the fonts aren’t loaded.

> The following seems to work, only that there is a fallback to the fonts defined as upright fonts (which are in fact italic fonts) for the \em parts which seems to be the default behaviour if no italic fonts are defined in the fourth bracket pair:

The \em command uses the slanted and not the italic alternative by default.

When there is no italic or slanted style in the font the regular style is used and when there is no bolditalic or boldslanted style the bold style is used.

You don’t need a serif and a sans font in your document, one of them is enough but math should be always present because some symbols like bullets (but you can force context to take them from the text font) are taken from math.

It doesn’t matter whether you use rm or serif in the second argument because the argument is checked and converted to a internal name.
