+## Workflow
+
+- New feature → clean branch from `origin/master` → push → PR on Gitea
+- Branch naming: `feat/description` (features), `fix/description` (bugs/docs)
+- Always branch from `origin/master`, never from another feature branch
+- Submodule changes: commit submodule update in parent repo (the parent commit pins the submodule commit)
+- PR title should describe the change; body should explain motivation + summary
+- After PR merge, delete the feature branch
