/* ==========================================================================
   layout.css — structural shells only. No component styling, no page styling.

   Two shells: the admin desktop one (sidebar + topbar + content) and the
   officer mobile one (.phone + navy header + sync strip).

   Ported from design/admin_prototype.html. All spacing uses logical properties
   (margin-inline-start, padding-inline-end, inset-inline-start, …) — never
   margin-left / padding-right — so the whole shell flips in Arabic without a
   single RTL override. See Section 8.2.

/* ==========================================================================
   Mobile admin shell — bottom navigation ribbon (js/shell/mobileNav.js)

   Admins still work on desktop (Section 1); this is the same app on a phone,
   not a second one. The sidebar and the ribbon are both in the DOM on every
   draw and exactly one of them is displayed, so rotating a phone or resizing a
   window swaps navigation without a redraw.

   Below the breakpoint the sidebar goes away entirely rather than folding to
   the top of the page: a full-height column of links above the content is the
   thing that made the phone unusable — the dashboard began a screen and a half
   down. The ribbon is fixed to the bottom instead, so the page starts at the
   top of the viewport and every destination stays one tap away.
