/* Briod's site header (#24)
   ==========================
   Markup: template-parts/header-briod.php. Behaviour: js/header.js.
   The measures are the design's, from design/header/README.md; where this
   file departs from it, a comment says why.

   Layout by width:
     ≥ 1360   logo on row 1; menu left and search · divider · buttons right on row 2
     993–1359 logo and search · divider · buttons on row 1; the menu on row 2
     993–1279 as above, with smaller buttons
     < 993    phones: 68px bar (logo, search, menu button), buttons under it,
              the menu as a full-screen panel
   Scrolled past (.bh-holder.is-scrolled), the header is a slim fixed bar.

   The bar is as wide as the page's content (Shoptimizer's .col-full: 1170px
   plus 2.617924em each side), not the whole window as in the design's frames,
   so the logo lines up with the content under it on wide screens. */
