The 'font-variant' and 'font-feature-settings' are intended as a way
to have site-wide defaults for a specific font, for example to use a
specific set of character variants consistently. As such, their use
is really for features that don't need to be overriden for specific
elements. If it's really necessary in some specific case,
'font-feature-settings' can override these:
code {
font-feature-settings: 'hist' off;
}
Another way to think of it is that the descriptors are *not* part of
the cascade, it's the equivalent of asking a font vendor for a custom
version of a font with a different set of default glyphs.
