WHO IS RESPONSIBLE FOR DESIGN TOKENS?

Summary from the TLDR Design newsletter

Design token ownership works better when responsibilities are divided according to the type of change rather than handed entirely to either designers or engineers. Designers can own primitive values, a mixed design-systems team can govern semantic tokens as a public API, and engineering can own transforms and platform-specific output. Automated checks can protect this structure by allowing value changes while flagging deleted or renamed semantic tokens that could break components and require migration.
