## Visual Decision

Shu infantry guard v1 is accepted as a shield-forward heavy infantry variant. The large shield, green lamellar armor, and compact sword make it distinct from the regular infantry and banner bearer while avoiding a named-hero silhouette.

## Technical Checks

- Base partial alpha: `0`
- Action partial alpha: `0`
- Base frame border hits: `0`
- Action frame border hits: `0`
- Base empty frames: `0`
- Action empty frames: `0`
- Base bbox width range: `171..201`
- Base bbox height range: `288..295`
- Base bottom range: `303..303`
- Action bbox width range: `171..261`
- Action bbox height range: `276..295`
- Action bottom range: `303..303`
- Local build: `passed`
- Local browser console errors: `0`

## Notes

The shield remains readable at 50px battle scale, and the idle/walk frames keep a stable bottom baseline. The action frames add visible bash, slash, command, hurt, and victory poses without border hits or partial alpha.
