/* ── Print ─────────────────────────────────────────────
   .content-scroll is a fixed-height, overflow:auto box (it's
   what makes the sidebar/topbar stay put while the page body
   scrolls) so by default the print engine only rasterizes
   whatever is currently visible on screen and cuts off
   everything below the fold. Reset the shell to unconstrained
   block layout for print so the full page content paginates
   normally.

   .sidebar/.topbar are hidden here (not left to individual
   pages) because .app-shell drops from grid to block layout
   above: with the grid gone, .sidebar (height: calc(100vh -
   48px) !important) and .topbar stop being grid siblings of
   .main and instead stack in normal block flow BEFORE it,
   each still claiming their full on-screen height. That
   reserves almost an entire page of blank space (just the
   collapsed sidebar's nav icons) ahead of the real content,
   pushing it to page 2 — the "blank first page when printing"
   bug. Hiding them here fixes it globally instead of relying
   on every page remembering to repeat this rule. */
