/**
 * Layout push: when a panel is open it OCCUPIES the layout instead of
 * floating over it — the app shell (#root, the AppFrame three-column grid)
 * gives up space. Only the center column is flexible (1fr), so the right
 * panel's width squeeze (margin-right on #root) lands exactly on the
 * conversation output and the input bar, like a VSCode sidebar.
 *
 * The bottom panel squeezes ONLY the center column — it must not cover the
 * app's own left sidebar or the right panel. DSH 0.1.x wraps slot hosts in
 * [data-slot] containers, so the AppFrame grid lives one level deeper:
 * #root > div[data-slot="root"] > div (the frame). Its grid items are
 * (frame > div:nth-child(1..3)): sidebarCol, centerCol, detailsCol, so the
 * vertical push lands on the center column alone. The fixed panels cover
 * the vacated strips, which looks seamless because #root's background is
 * the theme base.
 *
 * The sizes ride CSS variables updated by the Sidebar shell (0 while
 * collapsed); expand/collapse animates both the margins and the panel
 * slides on the same theme duration. Drags disable the transition so the
 * layout tracks the pointer.

   cluster spans right 10→70px, so 78px clears it with an 8px gap. Anchor on
   the header's slot host wrapper ([data-slot="conversation.session.header"])
