IQ Intel · Blog styles
================================================================
Shared by series index pages (/blog/signals/, /blog/magnets/)
and individual posts (/blog/signals/<slug>/, /blog/magnets/<slug>/).

Depends on iqintel-tokens.css and reuses several patterns from
index.css. To keep this file independent of the home page CSS,
the few nav and footer rules are duplicated here in minimal form.
