Visual Decision

Approved for continuous production run.
Direction: silver-white Xiliang cavalry commander on a pale horse, with long lance, gold accents, and blue/teal scarf details.
The 100% PC browser debug preview reads as a mounted lancer and not as a foot officer, generic cavalry, or Lu Bu-style boss.
The unit body is opaque and readable at battle scale without base rings, completion badges, or other external readability helpers.

Local build: pnpm build passed.

v1 established the mounted art direction but felt slightly too compressed in action frames.
v2 restores the cavalry/lance silhouette while keeping the horse, lance, and rider inside frame bounds.
