+// leaders that never cross, on a DETERMINISTIC worst case: a seeded synthetic country of 855 groups with stacked
+// duplicates and tight clusters (district geocodes are like that), long and short names, real photos on an allowed
+// host, the generic placeholder, and photos on a host that is NOT allowed (none of the last two may be drawn).
+// Rendered through the real poster-render.js (renderPoster), so it measures what prints.
+//
+// Asserts per format: every name drawn exactly once; leader crossings 0 (the renderer's own count, re-measured here
+// from the SVG); no overflow rows; photos = the pins with a real photo (60x96/66x66) or none (36x60).
+// --self-test: a renderer copy WITHOUT the lane clamp must FAIL the crossing arm (else the arm proves nothing).
+// Exit 0 pass, 1 fail.
