/* ============================================================
   Vanssay site chrome: the floating nav and the footer, shared by
   every page. The look is the home page's.

   The markup lives in each page between <!-- vn:nav --> / <!-- vn:foot -->
   markers and is written by tools/chrome.mjs. Edit it there, then run
   `node tools/chrome.mjs`.

   Every class is prefixed vn- and every property the chrome depends on is
   set here, so a page's own styles (bare `nav{}`, `footer{}`, `.btn`,
   `a{}`…) can't leak in. Loaded last in <head> for the same reason.
