/* --- Title / cover page ---
   The illustration is printed on the FULL physical 210×297mm sheet — it
   bleeds past the page's own padding, past the spine-safety margin, right
   into the gutter danger zone, exactly like a real book cover would. It's
   positioned directly on .page (not inside a padded wrapper) with inset:0,
   which — per CSS's containing-block rules for absolutely positioned
   elements — resolves against the padding box's outer edge, i.e. true
   edge-to-edge fill, ignoring .page's padding entirely.
   object-fit:cover so the artwork always fills all 210×297mm with no gaps —
   if the uploaded file's own aspect ratio isn't exactly A4, the excess is
   cropped (evenly, from the centre) rather than left as blank margin. */
