/*
   ELEMENT DIGEST (commented out for reference)
   --------------------------------------------
   #header
       Fixed top-level wrapper. Contains the top bar (.navbar) and the slide-out
       drawer (.menu). One full-width strip at the top of the viewport.

   .navbar
       The top bar: horizontal strip with site logo (.navbar-logo), Sign in/Join
       (.navbar-button), and search (.search-bar-wrapper, .search-icon-wrapper).
       Desktop height 55px; mobile 50px. Has ornamental glyph border (::after/::before).

   .menu
       The slide-out drawer/panel. Contains .menu-top (strip with hamburger/close
       glyph) and .menu-content (scrollable area with nav links). On desktop when
       open also shows .sidebar (narrow vertical strip with rotated logo). When
       closed, only .menu-top is visible (same height as top bar). Slides in from
       the left; on mobile it is full-width overlay.

   .menu-top
       The top strip of the drawer; same height as .navbar (55px desktop, 50px
       mobile). Holds the menu (hamburger/close) glyph. When drawer is closed this
       strip is the only visible part of .menu.

   .menu-content
       The scrollable body of the drawer, below .menu-top. Contains .menu-links
       (which wraps .nav). (.mobile-menu-cta was a fixed bottom bar; unused, commented out.)
       Height is typically viewport minus top-bar height (so content sits below
       the .navbar/.menu-top strip).

   .nav
       The list of navigation links inside the drawer (inside .menu-content). Not
       the top bar; it is the main link list shown when the drawer is open.

   .sidebar
       Desktop-only. Narrow vertical strip (e.g. 56px) inside .menu when open,
       with rotated site logo. Hidden on mobile/tablet (drawer is full-width, no
       sidebar). Its absence there may explain why article/content left margin
       overflows on mobile/tablet (no sidebar pushing content right as on desktop).

   .mobile-logo
       Site logo shown in the top bar on mobile only (hidden on desktop, where
       .navbar-logo is used).

   .mobile-menu-cta
       Unused: fixed bottom bar (Join/Sign in) was for mobile; rules commented out below.
