/* ============================================================
   Atypically — shared left rail for interior pages.
   The homepage frames everything in a fixed ink rail; interior
   pages used a top nav, so opening one felt like a different
   site. This restyles the existing <nav> into that same rail
   and insets the page. Each page keeps its own ground colour —
   only the chrome is held constant.
