What

Adds a per-repository logo system to the brand kit. Every repo gets a large-format mark: the constant green+gold "snake" frame with a single gold inner symbol that says what the project does — a strict two-colour system, differentiated by symbol shape. Generated programmatically in brand/build/ into brand/projects/<repo>/ (mark.svg, lockup.svg, mark-512/1024.png) for all 17 repos across the four families. The org marks in brand/org/ and every repo's favicon are unchanged — these are large-format only (docs hero, README banner).

Delivers the per-project system deferred in brand/STORY.md ("Act 2 — the family that never shipped").

Design

• Spec: planning/changes/2026-06-29.01-per-project-brand-marks/design.md
• Plan: same bundle's plan.md
• Rejected option recorded: planning/decisions/2026-06-29-project-marks-single-gold-inner.md (per-family accent colours — dropped as too busy; large-format-only means shape alone disambiguates)

Symbols

• DI (7): modern-di (dashed dependency graph) · that-depends (solid graph) · -fastapi (bolt-in-disc) · -litestar (star-in-disc) · -faststream (the FastStream delta, recoloured) · -typer (bold >T terminal prompt) · -pytest (stepped bars)
• Templates (2): reuse the org chevron mark
• Microservices/messaging (5): lite-bootstrap (rocket) · httpware (chain) · faststream-redis-timers (stopwatch) · faststream-concurrent-aiokafka (parallel lanes) · faststream-outbox (DB publishing broadcast arcs)
• Utilities (3): db-retry (cylinder + retry circle) · eof-fixer (document + ↵) · semvertag (tag)

How it's built

• brand/build/symbols.py — inner symbols + shared geometry helpers
• brand/build/geometry.py — project_frame() (parametric snake frame)
• brand/build/projects.py — MANIFEST (repo → symbol), project_mark, project_lockup, render_projects
• brand/build/raster.py — export_png extracted so render/projects share it with no import cycle
• Regenerate: uv run python -m brand.build.render

All marks are path-based (font-independent); a test asserts every mark uses only palette colours. 75 tests pass; just check-planning OK. Architecture promoted in architecture/brand-marks.md.

Notes

• modern-di-faststream is the only mark using a partner's literal logo path (FastStream's, recoloured); other integration cues are redrawn evocations.
• Wiring each mark into its downstream repo's site/README is per-repo follow-up.
