/* ============================================================================
   VOID HORIZON — landing overlays (split out of landing.css, web-design-pass)
   The full-res lightbox and the ship-stats sheet are native modal <dialog>s
   (modern-web-guidance: light-dismiss-a-dialog — closedby="any" + showModal(),
   with the guide's click-outside fallback in index.html). The review-mode flag
   UI (task-378) keeps its fixed-position chrome here too. Uses landing.css tokens.
