   The content column is the focal point and is protected for as long as
   possible: it is not reduced until mobile, when there is nothing left to
   spend. Everything else is sacrificed first, in this order:

     1. The page frame  — margins + rules. Genuinely wide monitors only; below
        that it is dead space, so it goes first and goes completely.
     2. The column gutters — collapsed in steps, which walks the content left
        toward the nav rather than narrowing it.
     3. The rail — the first whole column to go, once no whitespace is left.
     4. The nav — off-canvas at the mobile breakpoint, last of all.

   --toc-gap steps in lockstep with the left gutter (see toc.css) so the
   nav→prose and prose→rail gaps stay equal the whole way down. */
