/* Marks page: whole page stays fixed (sidebar, topbar, filters, pagination bar) —

   body ONLY (its box exactly matches the viewport, so it never cuts off the
   horizontal full-bleed .marks-section/.marks-table-wrapper rely on). None of the
   intermediate ancestors get overflow set — CSS forces overflow-x to auto whenever
   overflow-y is non-visible on the same box, and 'auto' still visually clips until
   scrolled, so setting it anywhere but body reintroduces the chopped-off-sides bug.
   .marks-table-wrapper clips its own rows via its own overflow-y:auto (below),
