   This is the width at which the desktop nav stops fitting on one row (it
   used to wrap onto a second and third row here), so the nav collapses into
   a hamburger panel instead. One row: brand, compact "Book a Strategy
   Call" button, hamburger. The nav links stay real <a> elements in the
   markup; below this width they simply live in a panel that is hidden (not
   removed) until the toggle opens it (assets/js/nav-mobile.js). The panel
   rules are scoped to html.js, so without JavaScript the nav degrades to a
   stacked block under the header row instead of disappearing.

   Selectors are prefixed with .site-header so they out-rank the equal-
