/* ============================================================================
   GLEE — STANDARD NAVIGATION + PAGE SHELL          v1 (2026-08-06)
   ----------------------------------------------------------------------------
   One navigation across every page. Before this, 36 pages carried 5 different
   shells and 3 different top-bar element names with 3 different link sets —
   so "where am I / what else is there" had a different answer on every page.

   Built entirely on the canon tokens (--bg/--panel/--ink/--sand/--line and the
   --patina-* additions), so it re-skins with whatever style is mounted and
   never needs its own colours.

   Structure this file assumes (injected by inject_shell.py):

     <header class="gnav">            standard nav — same on every page
     <div class="gtrail">             breadcrumb: you are here
     ...page's own content...

   No JavaScript. Group menus are <details>, so they work with keyboard, with
   screen readers, and with JS disabled.
