/* The nav's width is pinned here on purpose, so all three pages render an
   identical nav — this deliberately does NOT follow each page's own
   content width (which differs: 1320px on index.html, 1140px on
   movie.html/stats.html). Do not add a `.container-fluid` rule to this
   file; that would defeat each page's own content width instead of just
   pinning the nav.
   The max-width/margin below is qualified as `.site-nav .site-nav-inner`
   rather than a bare `.site-nav-inner` on purpose: this element also
   carries `.container-fluid`, and movie.html's/stats.html's own page
   <style> blocks (which set that class's max-width to their own content
   width, 1140px) load AFTER this file, so a same-specificity bare class
   selector here would lose to them on source order and the nav would
   inherit the page's width again. Nesting under `.site-nav` adds a
   second class to the selector, which reliably outranks the page's
   single-class `.container-fluid` regardless of load order. (Verified
   empirically — the bare-selector version measurably lost on movie.html/
   stats.html before this fix.) */
