/* ── Top bar (markup injected by topbar.js) ── */
/* The bar's wrapper must stack above the page-content .wrap (both are
   position:relative siblings), or dropdown panels paint underneath.
   Pinned at (0,2,0) below, with the bar's other geometry -- see there. */
/* Burger switches at 1020px, not 900: the French nav needs ~1000px of bar
   and would otherwise wrap to two rows in the 900-1000 band.

   The bar spans its own width, not the page's reading column: pages are free
   to narrow .wrap for prose (/try/ uses 860px) without squeezing the nav.
   .wrap.tb-wrap is (0,2,0) so a page-local .wrap rule cannot override it.

   Every property the bar depends on belongs in THIS rule, not in a bare
   .tb-wrap one. A page that styles .wrap in its own <style> block matches at
   the same (0,1,0) specificity and wins on source order, since the page's
   block comes after this file. max-width was pinned here; z-index and padding
   were not, so /try/'s `.wrap { z-index: 1; padding: 0 24px }` silently
   dropped the bar from 40 to 1 -- putting the Product dropdown *behind* the
   hero -- and shifted the bar's gutter by 4px. */
