/* Document-page overrides. Above 900px the homepage's own header (a plain
   three-column grid: logo | nav | actions) already works with no JavaScript
   at all -- JS is only load-bearing for the hamburger drawer below 900px. So
   this file only has to replace *that* breakpoint's behaviour: instead of a
   hidden nav a JS-driven `.is-open` class reveals, the nav becomes a second,
   always-visible row. The header also keeps a permanent background here
   (rather than the homepage's scroll-triggered `.is-scrolled` class) since
   these are plain dark pages with no hero image for it to sit over. */
