/* ============================================================
   nav-drawer.css  —  Zodianimal.com mobile accordion drawer
   ------------------------------------------------------------
   Phase 3. Below the bar breakpoint the .pn-burger opens a
   full-height drawer. The seven groups stack as an accordion; each
   group header is a <button aria-expanded> disclosure that reveals
   that group's rows (glyph + serif name + muted sub) as an
   edge-to-edge stacked list. Same card-free language as the desktop
   panels: hairlines and type, never boxes.

   Markup nav.js hydrates into (built from the pre-rendered panels):
     .pn-drawer[role=dialog][aria-modal]        (backdrop + top layer)
       .pn-drawer-sheet
         .pn-drawer-top ( .pn-drawer-brand + button.pn-drawer-close )
         .pn-acc
           .pn-acc-group[data-accent]
             button.pn-acc-head[aria-expanded]  ( label + .pn-acc-chev )
             .pn-acc-body   ( cloned a.pn-row rows )

   All tokens from tokens.css. No hard-coded hex. No arrows or dashes
   in content strings. 44px minimum touch targets throughout.
