The wall opened at the whole-wall view, where a card is 11-15 CSS px, under wallLod's 48 px photo
threshold, so every card showed its empty image slot: the README picture read as a blank grid (the
Driver: "zoomed too far out... hard to see the people groups"). It now opens at the top-left corner,
where the store puts the biggest clusters, with cards ~96 px wide. Checked headless with lodPlan on
the component's own geometry (2,107 groups, 53x40): desktop 1440x820 k=7.5, 77 photos; 1280x720
k=8.6, 60; phone 390x700 k=20 (max), 15 photos, all 'hd' and far under the 300 cap, so the memory
win holds. Reset Zoom still shows the whole wall. Rows were 3 units apart against 8 between columns
and left a 200-unit empty band at the bottom of the 4ft x 3ft canvas; 8 fills it exactly.
Built with BUNDLE=wall-of-people-groups only, then the tree; check:sri PASS.
