/* ==================================================================
   HEADER NAV - mobile burger drawer + prominent "Get a script" CTA
   ------------------------------------------------------------------
   Appended additively. Nothing above this banner is edited or removed.

   Header DOM order is:
       brand | nav#site-nav | .head-actions (CTA + .nav-toggle) | .nav-scrim
   which is also the desktop VISUAL order, so tab order == reading order ==
   visual order at every width and no `order` property is used anywhere
   (WCAG 2.4.3 / 1.3.2). Below 820px the nav is position:absolute and so is
   not a flex item at all, which means the in-flow mobile order is
   brand | .head-actions regardless of DOM order - the CTA and burger sit on
   the right without any reordering. The panel following its trigger in the
   tab order is handled in JS instead: nav.js moves focus to the first drawer
   link on open and restores it to the toggle on Escape / auto-close.

   All collapsing rules are gated on html.js-nav, which /assets/nav.js adds
   itself as its final statement. Without JS the nav stays in flow, visible and
   usable; the ungated <=820px compaction below shrinks that fallback to a
   measured ~152px at 375px (brand / links / CTA on three rows) against the
   original 160px. It could be squeezed to two rows by giving the nav a lower
   `order` than .head-actions below the breakpoint, but that would recreate,
   in the fallback, exactly the visual-order != tab-order failure the DOM
   ordering above exists to avoid - and this path only runs when nav.js has
   failed outright. Correct focus order everywhere beats 47px in a fallback.

   NOTE: .site-head{flex-wrap:wrap} (line 39) and .site-head nav
   {flex-wrap:wrap} (line 48) are the cause of the original 2-row wrap. Neither
   is edited in place and neither is switched off for the drawer: taking the nav
   out of flow already removes the wrap below 820px, and wrap is the header's
   only overflow escape at every width - with body{overflow-x:clip} there is no
   scrollbar to recover a clipped burger. See the note at .js-nav .nav-toggle.

     with JS the only in-flow flex children are .brand and .head-actions (the
     nav is position:absolute, the scrim is display:none/absolute), so there is
     nothing left to wrap in the normal case and forcing nowrap would buy
     nothing. It would, however, remove the last overflow escape: both children
     are flex:none, so if the CTA's rem-sized label outgrows its budget - a
     raised browser default font size, text-only zoom, or a Sora fetch failure
     falling back to a wider face - the overflow lands on the 44x44 toggle and
     body{overflow-x:clip} clips it with no scrollbar to reach it. With wrap
     intact the actions drop to a second header row instead, and nav.js's
     measure() feeds that taller box straight into --head-h. */

  /* THE PANEL. position:absolute (never fixed): .site-head has
     backdrop-filter, which makes it the containing block for fixed
     descendants, so a fixed sheet would be clipped to the header box. Being
     absolute against the sticky header also means it travels with the header
     and cannot break stickiness. left/right:0 resolve against the header's
     PADDING box, so this is already full-bleed - no negative margins.
     Closed state is visibility:hidden (not the `hidden` attribute, not
     `inert`): it removes the links from the tab order and the a11y tree with
     zero JS, it buys a close animation, and being media-scoped it can never
     leak to desktop the way a toggled `hidden` attribute would.
     max-height is derived from --head-h, which nav.js rewrites from the live
     header box on open/resize, so a raised root font-size can never push the
     last row below a scroll-locked fold. The literal is a pre-JS fallback. */
