+## Visual notes
+
+- v1 was attractive but too narrow for the approved visual baseline, so v2 widens the court robe sleeves.
+- Pale jade-green robes, official cap, bamboo slips, and sealed letter make Yi Ji read as a diplomatic civil officer rather than a warrior.
+- The brighter scholar silhouette stays distinct from Ma Liang's white robe and Pang Tong/Sima Yi's darker strategist silhouettes.
