Statement
The theme shall follow Semantic Versioning (SemVer). Minor versions shall be backwards-compatible. Major versions may contain breaking changes, which shall be documented with migration notes.
Rationale
As a Parent Theme used across multiple downstream projects, version stability is critical. SemVer gives child theme maintainers a clear signal about upgrade safety and establishes an accountability contract for breaking changes.
