/* ── Desktop collapse, measured from Linear: the layout slot animates (main column offset
   220 → the 8px gutter) while the rail translates fully off-canvas plus a 16px gap, both on the
   350ms shell curve and driven by the same state so they move in lockstep — the content card
   glides left rather than a panel flying off. No opacity fade. The rail keeps its width, so
   expansion restores it exactly. The page title bar's persistent toggle stays put; only its
   pane glyph animates. Hovering that toggle (or the 8px hot edge) PEEKS the rail: the same
   element lifts into a floating panel under the header row — card surface, measured corners
   and shadow — without a backdrop; clicking the toggle expands for real. ── */
