/* ============================================
   Simulation Theater
   Overlay that covers the lineup pool while a simulation runs. The pool is
   still mounted underneath (scroll position and grid state survive) — this
   just blurs it out and takes over the panel.

   Layout mirrors .generation-progress: centred column, one accent colour,
   the panel header (and its Run Sims / cancel button) stays reachable.
