Country Posters: the whole-India poster prints, every group named

India's card is no longer "too many to fit": it prints as the 60x96 side-lane sheet (all 855 groups named beside
the map, crossing-free leaders, real photos), whatever paper the wall asks for, until the shared size picker
offers 66x66 and 36x60 too. Its facts row reads "36 states and union territories" (English, from the wall
head's plural key). As ruled, the whole-India card offers no prayer list, packet or cards; the state cards keep
theirs. Its card preview is the real sheet.
check:side-lanes (+ :self-test, gates:pre): the three side-lane formats on a seeded worst case (855 groups,
stacked and clustered) through the real renderer: every name once, 0 crossings re-measured from the SVG, no
overflow, photos only where real; without the lane clamp the same data crosses 36 times, and the arm fails.
