Visual Decision

Approved for continuous production run.
Direction: disciplined Xiliang follow-up cavalry officer on a dark horse, with olive/iron armor, compact helmet, and controlled spear/saber poses.
The 100% PC browser debug preview reads as a mounted support cavalry commander, distinct from Ma Chao's white horse and brighter silver lead-lancer silhouette.
The unit body is opaque and readable at battle scale without base rings, completion badges, slash effects, or other external readability helpers.

Local build: pnpm build passed.

An earlier generated source with white motion trails was discarded because it could read like extra UI/effect decoration.
The accepted source keeps the mounted silhouette clean and effect-free.
