BATTERY / ASCII BRAND

Logo: agent inside a battery; the bottom cell protects a reserve.
Canonical character master: mark.txt (shared with dist/brand.mjs).
Avatar: logo-1024.png. Banner: banner-1500x500.png (1500 x 500).
Logo SVG uses native monospaced text; use PNG for identical rendering.
All artwork is character text, white on black. No live performance claim.
The banner portrait reuses the existing BATTERY ASCII face.
