Sub-brands declare relationship, inheritance, and lifecycle
Every offering explicitly chooses master-branded, endorsed, or independent architecture with governed overrides.
Guidance
Base family decisions on audience, trust, ownership, risk, lifecycle, and recognition before composing lockups.
Do
- Validate an acyclic ownership graph
- Version naming, migration, aliases, and deprecation
Do not
- Turn each campaign into a permanent sub-brand
- Treat missing inheritance rules as designer discretion
