/* Sticky is applied to #nav-root (the header wrapper each page injects
   the partial into), not the <nav> it wraps: a sticky element needs its
   parent to be taller than itself for there to be any scroll range to
   stick within, and #nav-root's parent is <body> (the full page), while
   <nav> itself would be wrapped by #nav-root, which shrink-wraps tightly
   to nav's own height with zero extra room -- sticky on nav directly
   never visibly sticks. Background is opaque and unconditional (not just
   once scrolled) because a CSS-only sticky nav has no scroll-state to
   key off without JS -- several sections (home's hero gradient image,
   case study's gray "Final takeaway" section) scroll underneath it, and
   nav text/icons are styled dark-on-light, so it needs a solid light
   background at all times to stay readable. */
