/* Land Edge — shared app shell (Spec 0018).
   ONE rail + header, fleet-wide, never forked. All color/texture comes from
   theme.css tokens (--c-*), so a theme tweak flows to every screen. The frame
   is a full viewport that does not scroll; only .le-content scrolls, so the
   rail and header can never come unstuck. A screen opts out with
   data-shell="off" (report/print views). */
