# Brand vocabulary Use **Sandwich Hime** as the primary project identity and **Hime-san** for its compiler/tool personality within that project, not as a separate framework brand. Use `himesan` for the command, `.sando` for source, `.sando.go` for generated Go, and `sando` for the runtime. Never call the project bare “Hime,” which can be confused with an existing Go framework. Never use `.san`; it belongs exclusively to the separate San language project. “Sando” evokes a sandwich and keeps both projects unmistakable in editors, tooling, and search results. The preferred truthful attribution is “Built with Sandwich Hime.” It is optional and governed by [TRADEMARKS.md](../TRADEMARKS.md).
