Current sources

Browser icon: frontend/public/favicon.svg; duplicate frontend/public/assets/favicon.svg; ICO fallbacks at both locations.
Brand mark: frontend/src/assets/logo.svg, frontend/public/images/logo.svg, frontend/public/assets/images/logo.svg, logo_dark.svg.
Footer marks: shared frontend/src/components/common/BrandMark.vue; frontend/src/webclient/chattermate.js imports the same source SVG for its error footer.
Preset portraits: 12 PNGs in frontend/src/assets/avatars/avatar-*.png; selected through AgentDetail.vue.
Paper-craft avatars: ten SVGs under frontend/src/assets/avatars/paper-*.svg; loaded by frontend/src/utils/orb.ts under the original stored variant indexes. Old generated data URIs are refreshed from avatar metadata at render time. Uploaded photos remain unchanged.
Additional candidates: PWA/install icons, default user/robot and role avatars, login/signup illustration. Third-party integration logos should retain official identities.

Design constraints

Use existing ink/porcelain foundation: paper #F4F1EB, ink #16171A, vermilion #B23A22, celadon #2E6A5C, brass #8A6326. Keep 16px brand marks simple and readable. No change to customer-uploaded images or unrelated UI. Visible product naming currently mixes ReplyPier and ChatterMate; do not infer a full rename from the asset request.

Concepts

A — Harbour / 港湾：restrained celadon speech-bubble mark, flat editorial portraits; low complexity; safe for business use, less distinctive. B — Seal / 回音印：vermilion reply seal, warm illustrated portraits and restrained AI medallions; medium complexity; best match to existing tokens, detail must survive small sizes. C — Beacon / 信标：ink/celadon geometric beacon, playful abstract AI companions and graphic portraits; medium complexity; memorable but more characterful than conventional support branding.

Each board shows brand mark, compact lockup, 16/32px icon simulation, chat footer/header application and portrait/AI avatar samples. Typography follows the existing Hanken Grotesk / Chinese sans foundation; only the concept headings may be editorial.
