Visual Decision

Approved for continuous production run.
Direction: imposing red-and-black warlord boss with heavy armor, long red plumes, dark cloak, and a large fangtian-style halberd.
The 100% PC browser debug preview reads as a unique boss at battle scale, distinct from Guan Yu, Zhang Fei, Jiang Wei, and generic cavalry/infantry units.
The unit body is opaque and visible without base rings, completion badges, or other external readability helpers.

Local build: pnpm build passed.

v1 had strong art quality but made some action frames too narrow.
v2 keeps frame safety while restoring the halberd/action silhouette for better 50px readability.
