1// nx_grid_demo.nx -- renders a real display:grid page (6 cards in a 3-column grid -> 2 rows) to a viewable
2// PNG via the full sovereign pipeline, so grid layout is confirmed in PIXELS (not only asserted geometry).
3// The page's own <style> supplies display:grid + grid-template-columns (multi-token value) + card colors;
4// the UA reader sheet adds the h1 bar. 100% sovereign. license_tier: ORIGINAL
