 1. Move all @media queries to bottom of document. Better in one place at
 the bottom for both specificity reasons (last in the file) and for
 organization (easier to find and modify).
 2. Simplify selectors to be less specific overall (things like {{{nav
 .main-navigation}}} become {{{.main-navigation}}}). (From matiasventura.)
 3. Add classes like {{{.site .site-content}}} in addition to the set of
 IDs already present such as {{{#page #main #primary #secondary
 #comments}}}. This allows elements selected with {{{#content nav}}} to
 become {{{.site-content nav}}} -- making things much better for child
 themes to have things like other {{{nav}}} elements inside the content
 container. (From matiasventura.)
 4. Add inline comments next to each calculated rule with rem units and
 line heights, like {{{/* 12 / 24 */}}}. (From drewstrojny.)
 5. For bonus points: "with all the fonts rem based it’d be neat to see
 floated image margins match the text’s rem-based image margins." (From
 themeshaper.)
