+
+## Visual Decision
+
+Approved for the continuous batch run. v1 replaces the previous flat placeholder with a fully opaque Wu marine infantry sprite. The round shield, short dao, red lacquer helmet, and dark teal cloth read clearly at battle scale and separate it from archers, cavalry, and strategist units.

+- local build: passed
+- Local browser console errors: `0`
+- Local browser 404s: `0`
+
+## Notes
+
+The v1 sheet keeps idle and walk height stable, avoids cropped action swings, and uses the unit art itself for readability without external bases, rings, or badges.
